Sabotage during the group sing? You don't say, Simon!

I'm having a high school flashback to gym class and picking teams. You know somebody is going to be picked last, teams are going to get stuck with people they don't really want and that drama will surely unfold.

How odd that Rose ended up in a group with Bikini girl?

Oh, wait. Now I get why they do group sing.

Tatyana is having a meltdown, leaves her group, joins another group and then goes back to her original group.

What do you guys think so far?
