I was all la la la, an excuse for pron caps, la la la, until I came to the bit at the end that bounces back and forth between blue and orange. I know it was no coincidence they were blue in 314, since the creators had said they'd done color themes for each character/couple, and blue was Brian and Justin's. I love the way the two colors are balanced out the sledgehammer scene!
If you think about it, the Stockwell arc is when Brian and Justin become equals, and Brian fully aligns himself with Justin's world view. So it makes perfect sense to have both blue and orange in alternation in that scene. And I'd never noticed it before!
