I like how they are setting up Leonard Snart's eventual turned to becoming a hero. Having Daddy issues and using his sister as a bargaining chip to do his dirty deeds is sure to make anyone want to jump to the good side. He will always have that dark side, but this seems like a very plausible way to get him over to Legends of Tomorrow in an organic way. Seeing Dr. Martin Stein 'Flame On' moment was interesting and unexpected. So, I'm guessing that Ronnie is still inside of him and isn't 'dead', not that I ever expected him to be. But the Blue Flame rather than the typical Yellow Flame is what I find intriguing. The ending was great with Dr. Harrison Wells arriving through the portal from Earth 2.
