Everyone knows that wing tattoos are almost always tacky as it gets. But still, I'd love to see Malik drawing (With ink? With henna? I don't know, figuer this one out) wings on Altair's back and shoulders (like that: http://i44.tinypic.com/1z582yt.jpg).
Bonus points if it's a modern AU and Altair decides he likes it so much he's going to get it inked permanently.
