In the final altercation, the wine bottle jumps from Miranda's hand to the coffee table several feet away, which Gus then picks up.
At about 4:25 Shawn and Gus are playing back a recording of two gunshots on a computer that provides an oscillograph trace (time vs amplitude) of the recording. However the trace only shows one gunshot. It's completely impossible that the trace and the audio are from the same source. It's front and center, so it's difficult to miss.
Gus gets his chance to do a talk show, which he called "After Dark Talk". When Shawn calls a few minutes later as a caller, it is daytime.
