Alec flailed a little, trying to reach Xander. "Hey! You are not superior! You couldn't even get a sock away from me!"
"That's because I was trying to be nice and not hurt you," Xander pointed out. "I still haven't gotten it back, and I don't really need it because I have a bunch of black socks, but here I am." He reached around Alec's grasping hands and got in a good tickle on his sides, making him squeal.
