Ulquiorra took the drink without comment. His preternatural eyes caught the slight twitch of Urahara's hand toward his mug. Ulquiorra glared at the former shinigami and then took a swig.
He looked over at the two shinigami captains and found them deep in their own thoughts. Slightly irritated that no one seemed to be talking now that Ulquiorra wanted to, he turned his attention to the Quincy boy next to him.
"You know, I've been watching you and your friends for months now." He paused and then took another drink.
((OOC...yeah, I know Ulquiorra wasn't watching them in canon, but this is a bit of fun, no? XD))
