Detective Sousa has a way of speaking that makes it hard to tell if he's joking — but Graham is fairly certain he's not, any more than he's bluffing about being unable to leave. But of all the things he's said just now, it's the mention of Mad Libs that has Graham huffing out a disbelieving chuckle.

"Graham speaking: I haven't heard that one in awhile. I used to do those with my kids."
