Already lurking in his mind is the idea that they are just going to go and attack someone else now, that he needs to stop them before they can, but he doesn't manage to act on it. He's too relieved to have been reunited with his dad - and just in time, apparently.

"I'm sorry," he says. He's not really sure what happened here, but he's sorry that his dad got hurt and he's sorry that they got separated - he can't even really remember how it happened. "I got lost..."

Hearing about the enchantment later will explain a lot of things.
