I'm an engineer! I've been an apprentice since before I was ten. I was starting on my journeyman piece back home but here, I've designed some really incredible things.

[Winry could have said something flip like, 'Whatever he needs' but she's not really that kind of girl.]

I'm his automail mechanic. I built his arm and his leg...ahh...he has his flesh leg here. [Thanks Noi, but that's probably confusing Gansey.] But Ed still has an automail arm.

[Before you can ask, Gansey:] Automail is a specific type of prosthetic from my home. It connects directly into the nervous system and moves like a flesh limb! They're really incredible.
