Well Annabeth has always been good at reading people. I mean there are a few times during the PJO series or the HoO series where other characters have mentioned Annabeth having silent conversations with people. This could work the other way, as even you said that we knew she could do it before, so it isn't really a knew power. And as you said, I'm not convinced that Percy has earthquake powers. I think that introducing a new power now, with three books already down, wouldn't be a good idea. I mean lets say that Percy did use real, no room for doubt, earthquake powers; it would just feel like he is gaining powers as the plot requires him to. I'll admit that new powers are sometimes cool, but the characters should learn how to use the powers they have to the fullest.
