The kid's excitement is contagious, honestly. Luke smiles at the words regarding the buildings. He wonders why they put him in the bigger rooms- though, his thoughts immediately turn to the fact that he's going to be in a room, by himself. That realization bothers him, just a tiny bit. He'd actually gotten used to staying with his friend, pretty quickly, "That's great, that you have someone to stay with. It must be nice to have your brother, here, with you."

While hugging Diarmuid, Luke gives a faintly sheepish look, "Alright, I'll keep that in mind. Thanks, Diarmuid."

Well, it's certainly nice to have someone offering hugs. Though, he's soon distracted by the way the hug has him feeling...less tired. He'd still had his doubts, after all, about the validity of the words. What person would jump to believe such an insane story, after all? He notes that, after a moment, he's not actually feeling all that tired.

So, when he's asked the question, Luke's face might make it clear he's surprised, "Yeah, I do, actually. Thanks."

The surprise fades and he's simply tilting his head to the side, silently watching as the boy attempts to remember the name. Memory troubles- that sort of thing still, to this day, reminds him of his own childhood years. Growing up while being "unable" to remember his "younger years", "You don't remember his name?"
