AW~! I didn't look at her Dad's cutie mark in that episode, so I thought he was a blank flanked Stallion. °_° I rewatched the episode and thought it was an exploding rainbow toaster. I'm a disgrace. Cute picture by the way~!
Maybe Spike would try desperately to join them, but the stuff they do is too dangerous for him. So he tries sneaking into whatever they're doing and gets into trouble so they have to save him. he was thinking they didn't think he was cool enough but they were just worried about his safety
