I was impressed at how much backstory the writers gave Sif. I loved learning more about her because she is one of my favorite Thor characters.
I loved Fitz, especially when he basically tells Coulson everything. Skye obviously searched for super Shield agent with crazy Asgardian on Google, and that is how she found them in Vegas.
I was so proud of Simmons. She has come off a little shy before, so it is great to see her step up. I agree, the team will side with Coulson and Skye over May, but will not be happy about all the secrets.
