1. Why did Roy lose something when he wasn't even the one performing the transmutation?
2. Why would Al reject his body, even if it did mean not being able to fight for a time, when he knows damned right that being able to come back to get it would mean opening the gate again by causing something terrible to happen? (That's what his body meant when saying "Your return will bring nothing but despair and ruin").
3. Is Roy going to rely on Riza to "be his eyes", and let rip that pun the manga so frequently makes reference to? (cause she's a sniper and watching his back, get it?) Hell, is she going to die or somehow sacrifice herself in a way which allows Roy to have her eyes transplanted into his head? Because that would be the ultimate irony, and pure genius. Will that transmutation circle on her back have anything to do with that process?
4. Wouldn't it be ironic that since Roy is aspiring to be the Fuhrer, if he were able to acquire the "all-seeing eye" from Bradley after his defeat? Because that would be made of win, and would obviously solve his eye problem... From the very person he was looking to replace. Unfortunately it would probably mean he would have to become a homunculus, but probably a human one that ages, like Bradley. I'd have no argument with that. It's not like he'd be much different. Besides, that already turned one main character into one, what's one more?
5. Maybe defeating Father would be the key to getting back what everybody's lost so far (although unlikely), allowing us to enjoy a happy ending?
Who knows. Awesome chapter though.
