Now, on the subject of Saki:
Around 12:20 isn't it her who raises her arms and starts cheering? That is so out of character. It must have been on purpose though I don't see the point. Another possibility is that they intended to have someone else doing that (maybe Karina) and got them mixed up.
That's supposed to be Karina and not Saki. The BD version of that scene changed the hair color from Saki's to Karina's hair color.
