When I saw the episode where Rainbow Dash becomes a Wonderbolt (Congrats for her!), the scene where she was imitating Rarity made her seem like she was flirting with Soarin'. I'm not an official shipper, but I did sense that the SoarinDash shippers probably went nuts over that scene.

P.S. Second comment on dm29's browser. I hope we can talk again soon, dm29.
