Darnell: *studies him, his expression shifting subtly to something a little…not disappointed, but…maybe sad? He allows a small, crooked grin, commenting softly* We don't even know where human emotions come from. Who's to say what's a real emotion and what isn't? *it's clearly philosophical, he's not expecting Connor to answer that - he scratches a few more quick notes, pulls a deep breath, and gives Connor another, more genuine grin* Anyway . . . welcome back, Connor. I really am really happy to have you here. *on reflex, he offers his hand - he wouldn't even really be sure why if it were pointed out to him, just…seemed like the thing to do*
