Castle

Viewers have not seen a new episode of Castle since May.

Similarly, when this show returns on September 20, Beckett has not heard a word from her partner since he left for the Hamptons to complete his novel. Therefore, you can imagine her surprise when she bursts into an apartment to follow a case - and finds Castle standing over a dead body.

Holding a gun.

As you can see above, Castle looks equally shocked in this scene.
