Also the 'Skye/Ward are totally a younger Clint/Natasha!' stuff. Uh, only if you know nothing about Clint or Natasha's personalities. :/

I read this, made a sound of horror, my mom asked me what was wrong from the other room, I told her, and she made a face like she'd been sucking on lemons.

You can make a case for similarities between Clint and Ward, I feel, but Natasha and Skye? FUCK NO. They're pretty much opposite in every way that matters. (And it doesn't help that, imho, Skye is a fucking terribly designed and quite inconsistent character.)
