Trivia: At the end of this episode we see Claire grab a number for martial arts training from Colleen Wing. Colleen Wing will be a main character in the next Netflix series, Iron Fist.
Continuity mistake: When Missy goes to talk to Cockroach, in most shots his sling has a tiny bit of blood on the white strap, but in one brief shot before she leaves the strap is twisted and the blood isn't visible. It goes back to visible in the next shot.
Continuity mistake: When Pop shows Luke the photo of him, Luke takes it from him and holds it with his right hand, but in the next shot, he is suddenly holding the photo with both his right and his left hand.
Continuity mistake: When Luke snaps the broom into two pieces, it's not a clean break, leaving a few inches of bare wood in the bottom part. A few shots later when we see both parts again, it's a much cleaner break.
