Malfoid Wants to be Confessed To: Reincarnation is WarMalfoid sometimes hides her feelings in Parseltounge
I think you're misinterpreting those panels. It's possible we'll get a twist where this Harry has lost his memories, but the simpler explanation is that Malfoy didn't use a happy memory to conjure the Patronus, but a strong fantasy that served just as well. Harry himself did this in the books when he imagined Dolores Umbridge getting fired. They work off of strong positive emotions, not necessarily real memories.So both Malfoy and Harry are reincarnators. Very curious to how this will go though, especially when Malfoy seems to have her own memories of Harry when Harry, himself, was reincarnated from when he was a born no?
Reasonable conclusion that I can think of here is Harry losing memories or him not recognizing Malfoy from when he was a kid.
Perhaps that's why Malfoy jumped into the conclusions that the Harry that is currently present is not the same Harry she used to meet.
Besides, we never actually saw Harry's past and what he did before up this point
