The color of Alastor's tongue changes between purple and red several times throughout the episode.
When Charlie and Vaggie are in the limo with Angel Dust after the turmoil at the News Studio and the fight between Angel Dust and Sir Pentious, Charlie is comforting Vaggie after a dispute with Angel Dust. As she tells her that things will be okay, she starts to take off her red jacket to reveal a white shirt and black suspenders underneath. However, in the next shot, even though her jacket has been removed, you can still see the red material on her shoulders as she continues talking to Vaggie.
When Angel Dust fires the Tommy gun at Sir Pentious, no fire comes out when he shoots it.
