Pinkie talking, Rainbow's eyes on Twi.

You know, most (if not all) of these screenshots are out of context. (It's a kids show after all) NOT THIS ONE. Twi literally just said, "Maybe we should all settle in for a good night's sleep," then glaces over at Rainbow. (Yes, I caught it at an opportune moment.)

Enjoying the view Twi?

She likes to make Dash sweat.

More of an honorable mention. (Twi's probably just looking at the cake.)
