IF Fluttershy has a coltfriend...
"Fluttershy!" Rainbow Dash shouted while looking for Fluttershy, "Fluttershy! you know playing hide and seek in the time right this is creeping me out!" Rainbow Dash shouted, when she take a peek on upstairs window, there she is! with a pegasi that's new to Ponyville! instead of intervening their conversation Rainbow Dash thought *Maybe I shouldn't tried to scare them* so instead of pranking him and Fluttershy, she just knock on the front door as normal pony would do...
"Coming!" in a few seconds the stallion fly behind the the cottage into the everfree forest, while Fluttershy saw Rainbow Dash she said "What are you doing here Rainbow Dash?" she hid her blush...
"You see, Tank had a crack on his shell, by any chance do you have anything?" Rainbow Dash asked, while Fluttershy was talking, Rainbow Dash got distracted by a flying pegasus going to the everfree forest! "Uhm, Fluttershy do you know that pegasi?" Rainbow Dash asked...
"And I'm so-" she stopped and blush a little and she hide her blush and said "What?" Fluttershy asked...
"There was pegasi flying into the everfree forest and I've never seen him her before, do you know him?" Rainbow Dash asked...
"I haven't seen him before" Fluttershy lied!
"Ok... about the shell?" Rainbow Dash started.
"As I said moments ago, I don't have any and I'm so sorry" Fluttershy continued.
"Ok... well I'll be going now!" Rainbow Dash felt the awkward moment of her life! and she thought *The blush seems obvious that Fluttershy have a relationship with that stallions, I think I should tell Twilight about this!*
