(by the way, every companion I've had so far comments on this statue)
There are a couple spots like that. Once I get more places for the companions I may put together a list of common spots. One of the things I'm curious about is whether the 1st companions you get actually have more comments or if it's just that you literally run around with them more. I think they have more comments cause there have been spots I've gone back to for whatever reason with a companion I picked up later and they're pretty silent.
