Honestly, Oswald can't blame Ed for wanting to keep his distance. It makes sense, considering the outburst.

Initially, he gives a bit of a resigned but understanding nod, the tip of his tongue pressing between his dried out lips in a kind of nervous attempt to dampen them.

Then, Ed speaks again and he looks up. Ed, and his genuinely questioning nature.

Oswald swallows before he can even start to think of what to say in response, though he finally settles on his more mask-like smile to disguise whatever complicated feelings he is having as he moves on arm carefully toward Ed's seat.

"If you would be amenable to it, yes."
