Who fits best with leo?

I think piper

A character who has not yet been introduced.

I hate to say this, but Rick Riordan has not invented a character that Leo could be with. They are all to serious. I hope that Rick will make someone for Leo in the 次 two books, and possibly one for Nico.

Hazel.

The character who doesn't make Leo feel alone. Does this character exist yet? No. >.<

If タリア was a option the would have the most B.a.m.f kids ever.
Sorry, two of my お気に入り character's. Fusing them with be like Greek 火災, 火 molotov's, infinitely kickass

my opinion: Piper

in reality: a character who has not been introduced yet

Uh, ME, duh!

Reyna. I like to think that, if they got together, they'd be a bit like Romione.

Calypso. They have so much in common.

I'm sorry people but I think Frank's gonna die. Think about it: It keeps saying in the 本 that his life's gonna burn short and bright, so I think Leo's gonna end up with Hazel.
