Here is kind of how I see things. On the Greek side we have Percy, Annabeth, Leo, and Piper. On the Roman side we have Jason, Reyna, Hazel, and Frank.

Who will like each other? (Greek to Roman)
Percy will get along with Leo, but be neutral toward Piper. Annabeth will most likely get along with Hazel and Frank. Leo will get along with Hazel and Percy, but not Reyna or Frank. Piper will get along with Hazel, but not Reyna.

Who will like each other? (Roman to Greek)
Jason will most likely form a rivalry with Percy, but respect him. Reyna will get along with Annabeth, but not Piper or Leo. Frank I don't think will get along with Leo. Hazel will get along with Piper, but feel weird around Leo.

This is all just speculation for characters that haven't met yet in the series. I'm basing most of this on their personalities, like Leo is the funny one, meaning he wouldn't get along with the serious type (Frank and Reyna). If I didn't mention someone's interaction with someone else, it is because I think they will be neutral toward each other
