I think that the most important connections are between Hazel-Frank-Leo and Frank-Percy. There's a connection between Piper and Leo because they have met before finding out they were demigods (although seriously I don't understand why this is so important but moving on) however that doesn't mean there's a connection between Piper-Hazel-Frank just because Piper is friends with Leo.

Annabeth is dating Percy but that doesn't mean she's connected to the rest of them. Frank and Hazel don't even know her and it's not like Jason, Leo and Piper are her biffles. I would say that a connection between Percy and Jason would be more based on the fact that they literally switched places and thus were connected to both camps ultimately connecting them together.

You know curios thing is that the person who everyone is connected with is Reyna. Yes, I know I've been mentioning her a lot but I'm basing my opinion on facts. Reyna knows both Percy and Annabeth since they were the ones who destroyed the spa. She knows Jason the longest (4 years already). She was the one that allowed Hazel and Frank to join the camp. Remember that it was mentioned how Nico went to her regarding Hazel and Jason was still in the fifth cohort at that time so he wasn't a praetor. The person who connects Reyna and Piper is Jason. Possible gf in Camp Jupiter and now possible gf in Camp Half-Blood. The last one would be Leo but think about Reyna's hounds. It's trivia, I know, but they do seem to be a lot like the ones given by Hephaestus to King Alcinous and Hephaestus is Leo's dad thus linking them.

Of course it depends a lot on what people understand by connections. If you think about it everyone is connected to everyone it's just that I thought the ones I've mentioned were more...peculiar connections.
