I'm honestly surprised that we're getting another season! In this case I think it can be directly credited to ABC being under the Disney umbrella with Marvel.
I'm really hoping that we see the formation of SHIELD this time.
With all of their attempts with AoS to tie in to the constant series of movies (and now talk of an AoS spinoff that will likely do the same thing), they almost have to do something along those lines.
Make that January 19, 2016, for the start of S2. President Obama has scheduled a State of the Union address for January 12 and ABC has decided to delay the start of Agent Carter by two weeks rather than run the 1st episode, have the 2nd scheduled episode bumped, and then have to re-air it.
That's a shame. I really liked there being a Marvel period piece and felt like there was so much they could've done with it. Hayley Atwell has been already picked up for another series.
