It is mostly a joke, but also not in some ways. Alcide can get very overprotective of people to the point that he cares more about their welfare than his own. And he has never been one to cower from the almighty computer even since the first day he arrived here. "Don't worry about me. I'm always in a little bit of trouble." A true statement if there ever was one, but also said with the kind of amusement that speaks toward the fact that he likes it that way when there's a dictator of a computer to rail against.

It's when she says the word 'dream' that things click for him. He'd dreamed about her. She must have dreamed about him. What did she see? As she explains the answers to that question, Alcide can see those memories vividly in his mind. She's not wrong about either of them - and that last one, what a horrible thing to see. Alcide remembers it all, especially how he felt. Feelings seem to linger so much longer than anything else, don't they?

"I dreamed about you too. I was... you, I guess. The reaping... which I didn't understand completely. But they took your sister after they called your name." Prim's utter fear and devastation is still such a palpable thing in his mind. No kid should have to feel those things so strongly. "And then you were helpin' people, a medic maybe. And you - there was an explosion." He looks at her, waiting to see if all of that is as true as what she said about him. Because if so, that solidifies the fact that someone has been messing around inside their heads. It solidifies the fact that someone here is capable of manipulation in that way and Alcide is not okay with that.
