When she walks away, Mary notices a man in a black van parked across the street.

Des thinks it's all going but then Joshua stumbles away from Kailey, vomiting blood. Des rushes to him and when Joshua asks him for the pento, Des tells him he got rid of his supply. He calls Mary and she agrees to meet him at Josh's house with the pento.
