Rex is already at the restaurant when Ana arrives, although he's surprised to have gotten there on time, since work ran a little late, then he had to take the train home to change clothes, and that took longer than planned... (Okay, so it took longer than planned because Rex isn't quite used to the train schedule yet, but shh.)

Now, he's sitting at their table, still smoothing down his hair and trying to look presentable. He glances up when Ana approaches the table, then stands to greet her. It's the polite thing to do, and Rex is nothing if not... Well, okay, he's not the most polite person, but Ana's his sister.

"Hey." His lips quirk into a smile, then he points to the bag and arches a brow. "You know Catenrat was last month, right?"

That's right, Catenrat. He's learned the lingo.
