During the diner scene with the Hale brothers, Zobelle, and Weston, a piece of black electrical tape continues to appear and disappear from Deputy Chief Hale's radio. The tape, it seems, was supposed to be covering the "Motorola" name, but does not appear in this episode except in this scene.
When Gemma Morrow is talking to the Wayne Unser outside the hospital, we see two shots of her right jacket sleeve. The position of the zip on the cuff changes between shots.
Gemma is shown twice during Bobby's welcome back party, even being spoken to by Weston as he leaves. At the same time, however, she is at Jax's home watching Abel and being kidnapped by The League of American Nationalists.
