One-Sided Love, One-Sided Episode

Just as I expected, nothing special between Phineas and Isabella at all, even in the second Christmas episode. What did you fans expect anyway? Like I said, the movie had its chance and blew it completely, so there's no hope at all. Maybe Isabella should give up, like she could have in "Summer Belongs To You". There's no way. But that's not the point of this post, so let me get on topic before I lose track of things. The real deal is that the episode is somehow already up on iTunes as a single episode instead of a paired episode! Now that is something unique and has never been done before on the Phineas and Ferb selection on iTunes. But again, I'm still wondering here... what's going on?
