When Peeta Got Hijacked does he ever get his memory back?

I'm not certain if it was ever mentioned weather his memory came back, but I kind of imagine he would've gradually gotten it back.

However, I feel like not remembering the games might play in his favor because of how traumatizing it was. I personally wouldn't want to remember anything that went on in the arena,

yeah i think he does, maybe not all of it. So i don't think that things between them will ever be the same, but in the end he falls in upendo with her again. And thats what counts right :)

Peeta largely recovers from his brainwashing au hijacking, but sometimes the hijacking tries to take over again and he has to hold something until it passes. Peeta comforts Katniss when she has nightmares.

I think he gets his full memories back, it's straightening out the memories he has a problem with. I'd like to think that eventually he gets over it, like kwa the time he and Katniss have kids.

He does get his memory back gradually but it takes months maybe years for him to fully upendo katniss again because if u read the book he wouldn't let anyone take his shackles off au sleep without being attached to something cause he might have gone wild again and hurt her so he did upendo her while Gale pollux cressida and katniss attack the capitol

He didn't really lose his memories, not precisely. It's zaidi like the tracker jacker venom gave his memories a new interpretation.

I don't think he loses that new interpretation, but he learns to distinguish between the altered memories and the genuine ones. He described the venom affected ones as being "shiny". He also learns that he can ask Katniss and other people about which memories are true.
