Dennis had been told that the temple was one of the places to be to quiet the mind. He hadn't known just how literal that was until he set foot inside.

"Holy shit," he mutters with some amount of awe; the quiet is deafening after so long of having no say in the matter.

It really is saying something, that he doesn't realize someone else is present until he spots Angel moving and the area getting a little bit brighter.

The corpse shall be approached! And only then does something ping in Dennis' brain, like he's just been flicked in the back of the head. Like, y'know, that this guy is, in fact, the walking dead.
