[The snakes are like an incredibly accurate read for Atem's actual mood, which is something Ryou hadn't known he would be so grateful for (in very specific situations), so when Atem starts explaining about the graveyard, he can tell that there's something more to it. It's not just looking for basic info.

And he's right. The answer is...very upsetting.]

Steve...is dead?! But he...he never struck me the sort to get into trouble with another monster!

[It had to have been another monster, because humans didn't seem to be strong enough to stand up to them unless they were empowered by something happening during the middle of the month.]

I'll go with you. I like graveyards anyway but...are you going to be okay, Atem?

[He's very concerned now.]
