All theories are to be placed in the relevant folder. Beware, for unmarked spoilers for Child of the Storm, Chaos Reigns and Ghosts of the Past abound.
- Confirmed in chapter 80, though the conversation is more along the lines of mutual regret at their failings as parents.
- Chapter 2 of Ghosts of the Past confirms this, though Crouch seems to have his own free will.
- Happens in Ghosts of the Past, though SHIELD and the Avengers are unable to assist thanks to the Red Court's Batman Gambit.
- Mostly confirmed, but the specific method laid out here is Jossed, as is the second reason, as he is very explicitly not the Sorceror Supreme anymore (in fact, one of the missions/errands he pulled off while presumed dead was only possible because of that) and he openly revealed his survival to the Avengers, et al, as well as Dumbledore, McGonagall, Ron, and Hermione just four days later.
- The equally mysterious Spitfire I.
- Especially since they Never Found the Body and there's also a throwaway line in chapter 21 that says that "she was close to unstoppable with a sword," and according to a blink-and-you'll-miss-it line in chapter 40, she was a time traveller. Hmmm...
- Peggy Carter, who disappeared in the 60s. And according to Doctor Strange, it's "wibbly wobbly timey wimey".
- Saber, from Fate/stay night, since it was said that the Lady Knight is trapped on her endless quest. Probably a long shot, but it does match with Saber on the verge of death after the Battle of Camlann in her home series forming a contract with the World as a Counter Guardian for a chance to claim the Holy Grail in order to redo her life so that she would never become the King of Britain and save her kingdom from ruin. Trapped on her "endless quest" for the wish granting cup, this as explained in the typemoon wiki happens: "She jumps forward or backward in time from the moment of her death, and returns to that moment upon obtaining or failing to obtain the Grail. Should she claim it, her time will flow again and she will die just as history has recorded. Should she fail, all her memories are returned to her body, and she can either continue her search for the Grail or cancel the contract should she find a reason."
- Jossed by Word of God, who isn't much of an anime fan.
- In chapter 78, he seems about to do exactly that, while Dresden tries to hide behind Wanda (which, since he's over a foot taller than her, is an enterprise doomed to failure), but Wanda just glares at him and says, 'Father, don't you dare', whereupon he backs down.
- Though while Magneto has been established as despising the Hellfire Club and frequently purging its members, Voldemort seems to have ruled out direct confrontation with the Avengers for the time being.
- He's certainly become a secondary character, and does indeed ally with Wanda and Dresden to fight Riddle and Selene. So, kinda confirmed.
- Well, she got the blood transfusion from Harry at the end of Bloody Hell, so we'll have to see if that does anything.
- Afterwards, he seems to have pulled himself back from the edge, but it's indicated that he's still not entirely all there.
We know Wanda struggled with her powers when she was younger, so it's possible she caused something M-Day-esque resulting in the 'births' of Tommy and Billy. If this event was then undone, possibly involving reverting the timeline Wanda created, then the description could fit. At the very least, the Young Avengers program has been mentioned, so there's a connection to Billy implied already.
Billy has a very, very similar story to both canon and COS Harry; a seemingly ordinary boy who was actually born under extraordinary circumstances and given incredible supernatural abilities. In canon he's a future Sorcerer Supreme, and his powers as the Demiurge are at least enough to put him in the same power ranking as Harry, Clark and Maddie.
Aside from that, Harry effectively has three power sets. His physical abilities, his psychic abilities and his magical abilities. Clark and Maddie both outclass Harry in one aspect of his powers, so it would make sense for the third child to be his superior magically.
Also I just really, really want it to be Billy.
- Could also be Kara Zor-El. I don't know too much about her comics incarnation, but I believe that she could be "a memory of Krypton," with her rocket trapped "in a cocoon of frozen time."
- Especially since the Jesus appearance seems to have gone down pretty well. Thor and Loki also mentioned being friends with them back in CoS.
- Peggy disappeared around the same time as the Angel of Cuba incident (and is not confirmed to be dead).
- It's been outright stated that the First Class of X-Men know who or what the Angel of Cuba was.
- It's been very strongly implied that the First Class of X-Men know exactly what happened to Peggy - especially since Alison Carter, her daughter, was one of their number.
- It's also been very strongly implied that Harry was the Angel of Cuba.
- According to Doctor Strange, what happened to Peggy is "wibbly-wobbly timey-wimey"
- Put all of that together and it seems pretty likely that when Harry returned to his present, Peggy ended up joining him.
- Jossed. A passing mention in Ghosts of the Past notes that he's being passed off as having been kept on ice by HYDRA and experimented on as a mixture of trophy and guinea-pig. He's well regarded, but the general public doesn't know about the Winter Soldier aspect of his past.
- Jossed. She is not, in fact, the Extreme Doormat Carol sees her as, and her motivations for wanting to stay away from combat are less fear, more a desire to make good rather than fight evil. Equally, as she explains, she wants to keep her daughter away from that world for the entirely understandable reason that she's seen how it can destroy people - but once she realises that that is impossible, she instead resolves to support her and be proud of her.
- Jossed. While Jean-Paul and Clark teaming up would've been awesome, Clark isn't directly involved in the arc beyond that visit, and Jean-Paul's involvement is also relatively brief.
- Jossed. She removed it and hid it in the phoenix feather Harry wears.
- While this would explain a number of things (the sense of humour, the fondness for Wanda, his utter disdain for authority, the monomaniacal obsession with making his failure over Maddie/Rachel right, and the raging hatred for Essex), this isn't the case. However, Word of God has it that this actually was the original plan, but it became too complicated (which for Nimbus is really saying something) and depressing, so it was cut in the grand raft of offscreen changes some time back.
- As yet unconfirmed, but as of chapter 80, he has linked up with Selene. Considering that he later dumps her as soon as he's got what he wanted, and only allies with others, such as Dracula, to use them for his own interests, it seems most likely that he's acting on his own.
- Jossed as of chapter 61 of Ghosts, where Strange mentions that he's disposed of the Black Council—they're either being cured of Nemesis by Mab, or else being dealt with by Wanda and Dresden.
