[ he's aware of the danger he's putting himself into. He knows how the Order works--but other than the branch in Kaisou, what has the Order ever done for him? Kidnap him from his family with threats of sealing away the entity keeping him alive, forcing him to go on do-or-die missions, to fake his death, lose his family, the goal he'd worked towards his whole life...

No. as much as this is to help one of his friends--one of his Only friends outside of the Order--it was also spite. He was doing this to spite the people who had ruined his life. And boy can you run on spite for a long time. ]

...I know. Between you losing your family by being transported here, a world hundreds of years in the future. Finding out you have--had a family but are unable to hold it in your hands any longer.

I have memories of a past life where I had a family. Even a son, too. But that was a life lived and gone. You didn't get to participate in any of it, and there's never a promise you'll ever get to go home from this place.
If any man in Kaisou deserves to drink himself silly, it's you, Edward.

And as such--as your friend.
I'll see you safely get home. No matter how much of a silly drunk you become, no matter how much of a handful you become.

I'll even drink with you.

I can't get drunk still, but. It's the thought that counts, isn't it?
