In episode 8 first season
When she have a SEX with Ed
Episode 11: Miracle in Rush Valley
In brotherhood, it is 8
It was episode 26.
That would be episode 28- Heart of Steel. I might be wrong about the number, but it is called "Heart of Steel" because it is my personal favorite episode.
Winry tries to shoot "Scar" in episode 22 of Fullmetal Alchemist: Brotherhood.
Winry works with her grandmother in her automail shop back in Ed and Al's hometown, Resembool.
On the last page of Chapter 108 of the manga, Journey's End, is shown (among others) a photo of Ed, Winry, and their two kids.
It is the second episode.
Nope they're childhood friends
I would have to say chapter 108, "Journey's End," when Ed awkwardly proposes to Winry.
In FMA: Envy probably did meet Winry, because in the episode of when Edward was fighting Sloth, he turned into Winry. In FMAB: I don't think Envy met Winry, but I might be wrong. I finished watching it, but I kinda forgot.
