RWBY/Fridge

Fridge Logic

 * What happened to all the friends Yang had on opening day at Beacon, who she'd preferred to hang out with instead of Ruby?
 * In episode 1 of volume 2, Ruby says "Four score and seven minutes ago", "I had a dream", and "I am not a crook" (the latter complete with Nixon's trademark "V" gestures) in the span of a minute or so. Remnant is not Earth, so where did she get those references from?
