All We Need is A Bucket of Yellow Hair Dye

Y'know, I do love how, after 4 seasons, they still manage to ramp up the stakes every time they do a two-parter focusing around fighting a villain. Not many shows can keep pushing it and not end up jumping the shark, but with the hella-awesome fight scene in Saturday's finale, they seem to be pulling it off pretty well! 

Roll on season 5!
