I thought they went a bit too far with Bulk Biceps.
The lesson was okay in this one. It only worked well because the Wonderbolts were jerks. But if they decide in a later episode to have Spitfire & Co offer a job to Dash, and Dash refuses it, I will be seriously upset. Sure, she'd see less of her friends, but... this is her dream. She's a really talented athlete and if she gets the spot, she'll have earned it. It's not that I'm saying that people can't ever turn something down for friends, but if one of my friends was offered their dream job and I'd see them a lot less, I'd still tell them to go for it, because holy crap that's their dream.
... That said, if she were to turn down the job because the Wonderbolts are jerks, I could understand that. I'd be upset that they were made into jerks, but...
Maybe I'm just reading too far into things. Other than that, the episode was fine. Nothing spectacular, but definitely not terrible.
Mr Khan; I think Derpy will be forever voiceless after Derpygate. Still, it's nice to see her around... even if I don't quite understand the fandom's obsession with her.
