I don’t think we needed a tip-off if we knew the title of the episode. Even if I didn’t, I’d think it was someone pranking her. Though I expected it to be a new character because Dash has developed her character way past that. I’m disappointed they didn’t bring in a new character then have Dash, who has already learned the lesson, comes up with the prank to get back at them. It would have made more sense. Not even season 1 Dash would do this to Fluttershy; did they forget she agreed with Pinkie that Fluttershy was off-limits?

When I first saw this creature, I thought that was iscord f**king around with Fluttershy; turns out Dashie is a bigger d!*ckhead than Discord

I think a lot of us recognized her voice.
