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 siguiente two books, and possibly one for Nico.

Hazel.

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

If thalia was a option the would have the most B.a.m.f kids ever.
Sorry, two of my favorito! character's. Fusing them with be like Greek fuego 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 libros that his life's gonna burn short and bright, so I think Leo's gonna end up with Hazel.
