[Twilight's about to ask how she's feeling, noting how tired she looks, but she feels Starswirl's eyes on the back of her head and turns around.]

[Megasoma, currently trying to see just how high he can lift the tent poles, turns to Twilight with a suddenly guilty expression. Sapphire, meanwhile, makes one final enormous yawn... and flops over backwards, releasing her poles.
The tent collapses on Megasoma, and Starswirl and Twilight both facepalm.]
