A physics problem: So Hyde just stabbed down on Moreau's chest with the full force of his body weight from a height of X-whoever-knows feet--should Moreau be dead right now? Probably! My band-aid explanation for this is that he's probably wearing several layers of protective Steampunk-y armour that keep his chest from collapsing.
On an unrelated topic: News! I'm going to be a director on season 4 of Star vs. the Forces of Evil! I'm really excited about it but also kind of hesitant to make an announcement because I could totally suck at this job and be fired immediately. So for now I will say: I am a director now, unless I get fired!!
