Sometimes I fear about Rainbow Dash's past ;_;.....I mean, in her most recent episodes, it seems that she has an almost DEATHLY fear of being alone or unappreciated. In her pet episode, she literally had a panic attack, and it wasn't really a funny kind. She could have pushed the boulder off at any time, but she couldn't even try cause she was too panicked.....that sounds like trauma. Does she even have parents? Her psych profile suggests she was an orphan.
True, but, there's just something about Dash. Despite being the most mentally grounded and rational of them(not the smartest, mind you, but she's smart enough), with the exception of maybe Applejack, she is clearly the most dangerous. I mean there is being brave, and there is automatic destruction on anybody if Applejack doesn't stop her. She attempted to attack Nightmare Moon, she tried to attack Trixie when she ran off with no apology, and in a recent episode, she threatened to crush the Flim Flam brothers. For a society immersed in good will, giving death threats isn't something you get just by being bullied a little when young.
