Troy - memes are like character bios with facts about them. I've written ones for Faye and Josh if you want them, just PM or email me your email address and they'll be on your way.
1) what colour are Ryder's eyes?
Blue. In my fics his eyes are grey-blue, but that's more wishful thinking than anything.
2) did anyone see him write? was he righ or left handed?
Pretty sure he's right-handed. I remember clearly a scene in
Gone where's he's talking on a cell phone, holding it with his right hand. I know it isn't as conclusive as seeing him writing, but you'd usually hold a cell phone with your 'good' hand, right?
3) did they play poker, or was it some other card game?
Poker.
Not sure about the other questions, sorry.
