Probably because it's like his time of being teenager has limits until he defeats Raphael
To be exact Peter original an old man, so I guess like fast aging for his hair
y'all read like the second chapter his hair already had that streak. I think someone in the comments said smth about how it just shows he's reliving and the artist confirmed it.
tbh i thought it doesn't had a meaning lol, but since at 94 there's a close up and it doesn't look like a streak anymore, i think i kinda get it
I thought that too but the artist did say it was just to show that he had gone back. But I am also like 90% sure he did not have it when the manhwa first started. I swear it got added in later, even went back and checked the early chapters and it was there but I swear it wasnt.
This is literally what I said a few days ago but everybody didn't agree with me, I thought it was losing my mind
Im so glad its not just me but Im seriously confused now cause i went back and it was there?!
or Soongu/Pietro's hair is probably slowly going white?
