Maybe Simmons went back to visit her parents. She was always calling them up... Or... could that have been... nah.
Coulson really seems under a lot of pressure (as he should be). His softer side from last season seems to be quite repressed, and they did a good job of portraying that.
Anyone else remember the side reference to potential allies in the UK? Wonder what to make of that. STRIKE?
And that opening sequence could've almost been a deleted scene from TFA, it was just that good.
Pretty sure that metal Mcguffin thingy had the alien writing on it, briefly.
We now have a Quinjet!
EDIT: Something sad that occurred to me after viewing: In the opening sequence, we're shown WWII-era Carter and Whitehall. At the end, we see present-day Whitehall. Compare and contrast with present-day Carter from TWS...
