He tries not to make too much noise anyway, but he jumps when he hears the first voice and immediately gets his back to a wall, freezing and listening. He rarely tries to make sense of anything splicers say, and even more rarely succeeds. This is no exception, and nothing about it strikes him as particularly odd.

Except, maybe, the slug-fucker part. It's obviously to do with ADAM-- everything they say's to do with ADAM. But he wonders vaguely who she's talking to, and why that would be her go-to insult. It just seems a little...specific, although it has a nice ring to it as insults go.

He lets it go, it's just crazy talk. Spending more time on it than he needs to is only going to make him crazy too.
