Alucard watched Lumi with a critical eye, but he listened to the Noah with a much more critical ear.

So they thought they could kill this one, did they? Lumi was, at least in Alucard's view, an Exorcist until proven otherwise. He wasn't intimidated by Alucard, either, which meant he was strong, at least strong enough that he didn't get initimidated.

If he was someone else's bodyguard, maybe he wasn't so dissimilar from Alucard, really. Now wouldn't that be interesting?

He wasn't stupid either. He didn't let Alucard stay lingering behind him, and Alucard moved to stay near Integra, without Lumi being between them.
