You offer Moondancer to help her get closer to Twilight, and mention that you know a thing or two about flirting.

Moonflower: "Not jus' flirtin'! Heehee!"

Moondancer: "L-look, I don't know where you got the idea that I needed help with... whatever it is you're implying, because I don't.

Anyway, I have some very important studying to get back to."

Sweet Biscuit: "Nice try, Trailblazer, but Dawn Break's already been working on that for years."

Sea Swirl: "Eh! Give it time."

The clock on the wall indicates ten to eight.
