Bravo, FitzSimmons. Well played! I kinda got the feeling that Jemma was up to something, but I didn't expect Leo to be in on it too.
Lots of revelations about the Inhumans and their community living in some place that looks like a part of the Himalayas. I knew Raina and Cal must've been taken to the same place, but what I didn't expect was seeing Jiaying, Skye's mother, alive. The whole dynamic about Skye's origin and biological nature now makes more sense.
Gonzalez is going out of his way to prove to May and others that RealSHIELD is not evil. "We're not the bad guys here. We're not holding you prisoners. We just need to open the Toolbox." But having a hostile takeover doesn't exactly demonstrate good intentions. Amidst all this chaos, I wonder where the "other" agents out in the field stand. Do they even know about Gonzalez and his team?
As for Agent May, I doubt that Gonzalez will be able to persuade her to join their cause. She's far too loyal to Coulson. She could, however, pretend to be on their side just to gain intel.
