Terry grabbed this compartment, assumedly with the rest of the Raventrio (but correct me if I'm wrong, Sarah and Heather!!). I assume they were pretty sombre because of Michael's dad. Notably, Terry had brought along a decent-sized lunch for the three of them, made by him and his mum, with like, all of Michael's favourite foods or something.
Apart from that, he would have gone around to greet some people briefly, I expect? And also stared at the journal a lot, he's now CONVINCED THEY USE IT TO MONITOR PEOPLE (hence why he hasn't been using it for a bit).
