Does Toph have a crush on Zuko?

In the episode "Serpent's Pass" Toph starts to drown then Sokka screams that he's comin' to get her. After he screams this, Suki jumps in the water to rescue Toph. Since Toph is blind she assumes it's Sokka who saved her and says, "Sokka, you're my hero", and kisses Suki. Also in the episode "Sokka's Master", Sokka feels left oout because he's not a bender and decides to train with a SWordsmaster. Everyone is bored without him, but when he comes back for a meteorite that he wants to make his sWord out of, Katara and Aang ask him to say something funny and they tell him how much they missed him. Toph says that she didn't miss him at all, then turns away and blushes. So yes, Toph does have a crush on Sokka.

In Avatar: The Ultimate Pocket Guide, a blurb about Toph says "Secret thing about Toph: she has a huge crush on Sokka!"
