Castle

When Castle and Beckett are on their way to meet the victim's friend Chloe in the playground, campaign posters for City Counselor Jeff Horn can be seen on pillars and walls. In a later episode, Hell Hath No Fury, Jeff Horn is murdered and Beckett and Castle look for his killer.

Goof: At the end of the episode, Castle is typing on his laptop. He then closes it and puts it on his desk. Seconds later, when he's looking at the photograph, you can see the laptop open again on the desk in the background. When the camera is panning out, it appears to be closed again.

Goof: When the detectives are watching the video of the elevator it shows the times Sarah was in the elevator. She went down with the laundry at 12:07PM, came back up at 12:14PM and back down at 12:48PM. The detective then says that no one else went down to the basement in the next hour except the lady who found the body. At home, Castle studies a copy of the video and learns two things, that she didn't have her cell phone with her on the 2nd trip down and that the 2nd trip took five seconds longer. Later when they are looking at the video again, they see Chloe in the elevator going down to the basement at 12:54PM, just 6 minutes after Sarah did.
