Well THIS wasn't too big a surprise...

Mockingbird has been cast for Agents of S.H.I.E.L.D.

But what was surprising to me was the who:

Adrianne Palicki.

I haven't seen any of her work, including the WW pilot, but I haven't seen Marvel Studios make a casting mistake yet. 

Speaking of casting...

John Slattery will appear in Ant-Man...as Howard Stark.

So at least part of it takes place in the (not too distant) past. That's cool. I guess Hank and Howard either knew each other or worked together. Which makes sense if Pym spent any time with S.H.I.E.L.D.

Here's what we know:

1) Agent Carter comes out in January.

2) Avengers: Age of Ultron comes out in May.

3) Daredevil comes out on Netflix...in May.

4) Ant-Man comes out in July.

Since AoS interacts with the films, lets make some predictions:

1) Mockingbird will appear in A:AoU, meet Hawkeye and possibly (at least verbally) fight Black Widow over him.

2) Dominic Cooper's Stark will say and/or do stuff that will be brought up/referenced by Slattery's Stark. Either that...

2a) ...or Anton Vanko will make an appearance.

3) It will be in the aftermath of A:AoU that other heroes (Daredevil, Luke Cage, Jessica Jones, Iron Fist and...Dr. Strange?) start coming out of the woodwork. As if an alien invasion in Manhattan wasn't enough.

4) We'll see some documentation or mention/reference of Matthew Murdock's childhood accident in AoS...because hoping for an appearance by Cox would be asking too much. Either that...

4a) ...or Coulson will mention to Skye to keep an eye on "a new crime lord building a power base in New York". Because an appearance by D'Onofrio would be asking too much.

5) Coulson et. al. will learn about an artifact that was kept under wraps by the SSR (most likely Zodiac) which will be the plot arc of the Agent Carter series.

6) At some point, Slattery's Stark will be shown making the recording seen in the Iron Man 2 easter egg.

But SO HELP ME...

...if they cast Caine as Cooper's Stark's Jarvis, I'm just going to lose my s#!t.
