That's true, but we didn't really get to know the new ones as well as the PJO ones. I mean, I would've liked if RR wrote some more about Dakota and Gwen. We know almost nothing about them. While back in PJO we knew pretty much about who is dating who and who likes and dislikes who. Clarisse and Silena being best friends cause Silena helped Clarisse and Chris get together.

We don't have that kind of background stories in HoO, and I miss them.
