Caspar's last name means little to him, and seems especially pointless in the Nexus. His full name is meaningless, as fake as the memories he was given when made a sleeper agent aboard the Chiron. But he has grown fond of Caspar. It's what Adia has always called him, he sees no reason to switch back to Five or another name of his choosing.

The comment on his drinking gets an eyebrow raise. "Can't or won't?" he asks curiously. The mention of a guitar gets a thoughtful nod. "I bet he'd like that. I can play a piano, but I'm also out of practice. And I don't know where I'd scrounge one up, anyway."
