Mouse is definitely my favorite Misha character. I bought Lost and Delirious to watch the girl-on-girl stuff (sorry), but I forgot all about that after I discovered Misha's character Mouse.
Since then, I've watched L&D several times, but I now skip through the scenes that Misha doesn't appear in.
Oh, I posted these pictures over at the Pictures of Misha thread, but they are so adorable and sweet that I thought they needed to be posted here as well.
