In the Blood - S1-E4
Continuity mistake: Karen is talking to Urich in a diner as he is drinking from a mug. As she is saying there has to be a trail, the camera is behind Urich and pointing at him fiddling with his cup. In this shot, he places his thumb over the rim of the cup down inside it. Then in the next shot from over Karen's shoulder, suddenly he is just holding the cup normally. (00:12:24)
Chosen answer: Castle picks up the newspaper from the pile of mail and carries it to the table. There don't seem to be other newspapers in the pile, and there should be more given how long he was away, so perhaps only that issue was put through the mail slot. Karen may have done it, but she seems to still think he was dead at that stage.
