Twilight Sparkle is lonely. So lonely, in fact, that she spends many months devising a plan to get Rainbow Dash to snuggle with her in the hopes that doing something so intimate would let Rainbow see just how much she cares about her.
It's been a week since Rainbow Dash saved Scootaloo after she jumped in to Ghastly Gorge and Rainbow Dash is keen for her to go back to school, as well as make good on a promise.
