A Cold Day in Hell's Kitchen - S2-E13
Continuity mistake: Before the last fight there are over 30 ninjas waiting for Daredevil and Elektra. Elektra kills like 5 or 6 of them and Matt struggles just with Nobu, but when the fight is over the rest of the ninjas are dead below the water tank.
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.
