[Cerberus flops down on his side, an open invitation for belly rubs.]

Normally he's guarding the gates of the Underworld and is a lot bigger. I don't think he has many chances to just be a regular dog... as regular a dog as he can be for having three heads. When he first showed up here, he was a lot more guarded, but he's become more relaxed over time, I think. Still protective though. [And Nico's become just as protective of the dog in return.]

I'm sorry that happened. [His words are genuinely sympathetic.] I've had a few experiences with memory loss... It's hard to remember you forgot something if you can't remember you forgot something in the first place. CERES usually... resets things after some time, if that's any consolation, so if you still don't have some back, chances are you'll most likely remember given some time.
