It makes sense that Alaric is alarmed, hell, Caleb was alarmed too at the time. But he was freaking out and running out of time, and he knew like two people in the city. He couldn't have just asked Alaric.

"I was careful?" He feels a little like a puppy caught with a toppled over potted plant. "And I'm fine." At least he thought he was. He's painfully embarrassed right now, though, and he's been trying not to think too hard about sex or the fact that he has to make it part of his life for the foreseeable future.
