I vote Trixie

Veronica, well, she's a nice girl, but Trixie it is more

Chloe, I think can be friends with Timmy in time when it is a child with the fairies

Molly, i do not know so much about her relationship with Timmy, appeared in only one episode

Tootie, i do not like, I find it too "immature"

Missy, I find it useless !, is not right that Timmy leaves Trixie for Missy!

Kimmy I think her in love with Sanjay, not of Timmy
