Now, this look could point toward a more human or grounded character with some sort of military or combat expertise rather than a multiversal threat. Still, it could also be a very elaborate ruse by a villain, so we can\u2019t just base it on looks alone. We need more to solve this much-debated mystery.<\/p>\n
The second thing we need to look at is what we have been informed about by reliable scoopers and outlets. The first instinctive detail we had was that Sadie would be an ally, given her on-screen presence as Max Mayfield in Stranger Things, but that may not necessarily be the case. According to her casting list description, she is a \u201csharp and free-spirited woman with a mysterious past, who is strong-willed, intelligent, and not easily intimidated.\u201d <\/p>\n
And given the recent trailer leak, it\u2019s clear she is no joke. But it also gave us a massive clue about her character. She\u2019s not necessarily on Peter\u2019s side, but it doesn\u2019t seem to be a full-blown antagonist either, given that she is currently under the watchful eye of Jon Bernthal\u2019s Punisher in the movie. <\/p>\n
Her character, at the very least, seems complex. And this very complex character is on the run from the Department of Damage Control, where I reported in my last exclusive that Tramell Tillman would be portraying the new head of the DODC<\/a>\u00a0and will appear in Spider-Man: Brand New Day intending to capture Sadie Sink\u2019s character because they believe that she is a mutant, or at the very least someone with unchecked powers.<\/p>\n Speaking of powers, recent reports have pointed toward her being a shapeshifter. And something interesting to note is that, in an interview with EW<\/a>, Sink herself said, \u201cA lot of people forget that hair color can change\u201d when asked about her role in Spider-Man: Brand New Day. Many people saw that as a reference to her hair color, but maybe she was slyly referring to the shapeshifter role. <\/p>\n In addition to that, there were reports of a female villain being attached to this movie, and one that could reportedly control the minds of multiple people at the same time, not to mention that, given the scenes from the recently leaked trailer, there seem to be a lot of trippy, mind-bending effects at play here. Very Doctor Strange-coded if you ask me, except that Doctor Strange won\u2019t be in this movie. And I can confirm that there will be hallucination-type sequences in this movie involving multiple characters, not just Peter Parker.<\/p>\n So, there\u2019s clearly a lot going on here, and judging by the dumpster fire of leads and rumors over Sadie Sink\u2019s role in the last few months, trying to pinpoint one single character might seem troublesome. <\/p>\n Scoopers and outlets within these circles, myself included, have gone from Mayday Parker to Shathra to Jean Grey in the matter of a few months, chasing every new lead that comes out of this set, and it seems like every new little detail that comes out contradicts something we have reported on before. It\u2019s why most scoopers are afraid of putting out there who they think Sadie Sink is portraying because, at the end of the day, no one likes to be wrong and have their credibility take a blow.\u00a0<\/p>\n However, in one of my late-night think tanks, as I like to call them, it hit me. What if all the leads coming out of this movie aren\u2019t misdirects? What if, instead of focusing on the smaller details, we looked at the big picture altogether? If all the leads are true, Sink would be portraying an antagonistic female character with red hair, some form of military training or expertise, a complicated past, telepathy, the ability to \u201cshapeshift,\u201d and classification as a mutant by the DODC. And I think we may have found our culprit.<\/p>\n Theory: Sadie Sink could be portraying Mary Alice Walker, aka Typhoid Mary<\/p>\n Probably not the character you guys were expecting, huh? Let me give you guys a quick rundown of who Mary Walker is and try to convince you as to why I think Sadie Sink is portraying this character in Brand New Day.<\/p>\n Walker was introduced in the comics in 1988 as a complex character from the get-go due to her troubled past of childhood abuse, which resulted in Mary developing alternate personalities through her dissociative identity disorder. Moreover, due to the deep psychological strain of her past abuse at the hands of her father, Mary\u2019s alter was able to awaken her latent psionic abilities, which were later revealed to be of a mutant nature.\u00a0<\/p>\n As time went on, she developed her telekinetic and telepathic abilities, as well as her prowess as a martial artist and close-hand-to-hand combatant. She became a notorious street assassin who caught the Kingpin\u2019s attention and became one of his most essential enforcers. She\u2019s had run-ins with the likes of Daredevil and Spider-Man. She has had a complex relationship with Daredevil, which eventually led to her becoming the Hand\u2019s temporary leader during the Shadowlands comic event.\u00a0<\/p>\n The evidence supporting Sink as Typhoid Mary<\/p>\n Already off the bat, this character is checking off multiple boxes for me. First, her appearance is similar to that of Sadie Sink\u2019s unknown character in the movie, with the red hair, similar bangs, and the military combat uniform. <\/p>\n Secondly, Mary\u2019s classification as a mutant in the comics, coincidentally referred to as Mutant Zero following the events of House of M, falls in line with the supposed mutant nature of Sink\u2019s unknown character in the movie and also supports the premise of DODC going after her because of her apparent mutant nature.\u00a0<\/p>\n Thirdly, her psionic powers match the apparent mind control sequences that we\u2019ll see in the movie, with multiple guards at one point being influenced by an apparent unknown force, and seeing how, in the leaked trailer, Sadie\u2019s character approaches these guards with arms open wide, unarmed, makes me think that she may very well have an ace up her sleeve that could support that. <\/p>\n Additionally, it could also explain why Punisher is helping her and why Punisher later tries to kill Banner. Not to mention, we also see Peter Parker go through some psychedelic, hallucinatory sequences in the trailer, as well as reports of other characters that will undergo these hallucinations, which could very well be the work of Sadie\u2019s character, if she is indeed Typhoid Mary.\u00a0<\/p>\n As for the shapeshifter portion of her skill set, it also fits in with Typhoid Mary, given Mary\u2019s diagnosis of DID. In the comics, whenever Mary Walker shifted into her Typhoid Mary alter, her appearance would physically transform, with half of her face transforming into a pale hue, with her hair and physique changing as well. This is very much reflective of individuals who have DID, although quite exaggerated. This also slyly connects to Sadie\u2019s previous remarks about her changing hair color.<\/p>\n What\u2019s also interesting about Mary having DID is that it gives a reason for Bruce Banner to be in the movie. It\u2019s publicly known information in the realm of the MCU that Dr. Banner has the alternate personality of the Hulk and was able to put the brains and the brawn together, allowing both the Hulk and Banner to coexist peacefully. <\/p>\n What if that is the main reason that Peter goes to search for Banner in Brand New Day? Knowing Peter, it\u2019s likely he had a run-in with Sadie Sink\u2019s character at the beginning of the movie as the sweet, innocent Mary before later encountering her villainous alter ego. If he becomes aware that Mary has alternate personalities, could that be why he goes to Dr. Banner to ask for help in helping Mary control her alternate personalities? <\/p>\n After all, it\u2019s highly unlikely that Peter would need Banner\u2019s help with Gamma radiation at that particular moment in the movie, and maybe Banner likes the idea of being able to help someone as Dr. Banner. Especially someone he can identify with that has a similar situation to his, instead of having to rely on the Hulk, and touch upon the subjects of overcoming traumatic experiences and coping mechanisms that can help her be a better person.<\/p>\n Another interesting connection here is the appearance of the Hand. Remember, in an earlier exclusive,<\/a> where I talked about \u201ca dark, mysterious female character\u2026 that had a Japanese-inspired cyberpunk aesthetic look, had a katana, and was associated with the samurai and shinobi characters (whom we now know are the Hand)? In the comics, Typhoid Mary was actually one of the leaders of the Hand during the Shadowland era in Daredevil\u2019s absence and used them to conduct illegal activities at the behest of Kingpin. And she used a katana in this era. So this is another box that checks off in favor of Sadie Sink being Mary Walker.<\/p>\n And lastly, if you\u2019ve read my Q&A here<\/a>, you may recall I mentioned that in a lead I was chasing, Sadie Sink\u2019s character could very well be one of the faces of the Mutant Saga. Typhoid Mary\u2019s history in Marvel Comics is interesting in relation to the mutant side of the comics, particularly because she was the result of an experiment called Project Psyche, aka Weapon IX. <\/p>\n I wonder, what famous mutant project came after Weapon IX was completed? If you guessed Weapon X, aka Wolverine, Sabretooth, and more famous mutant origins, then you\u2019d be right. <\/p>\n One rumor I had heard from a source regarding the whole Mutant Saga storyline is that it will eventually be revealed that the United States has been conducting the Weapons Plus program for many years in the MCU, and with the Mutant Saga knocking at our doorstep, the X-Men about to make their debut, and the possibility of Weapon IX being in an MCU movie before the introduction of the mutants, is too much of a coincidence to me.<\/p>\n The evidence against Typhoid Mary<\/p>\n Now, as always with these theory posts, I could be wrong here, and there are a number of reasons why. The first and foremost point one might bring up could be that we already had Mary Walker in the Marvel\/Netflix universe in Iron Fist season 2, and that character is technically still alive. <\/p>\n Now, we don\u2019t know whether the Netflix universe is fully integrated into the MCU or just an adjacent thing where similar events happened in the MCU. They selectively choose what did or didn\u2019t happen. It\u2019s most likely that the events of Iron Fist may not be 100% copied over in the MCU, and Mary Walker\u2019s storyline could be one of them.<\/p>\n The other point could be that she may very well be just an original character or some other character that we don\u2019t know of yet. But time will tell.<\/p>\n Who do you think Sadie Sink is playing in Spider-Man: Brand New Day?
