Luke's clone returned as quickly as it had gone. After giving old Mephisto the final '6' in a '666 blessing,' it returned to New York.
Recently, both Luke and his clone had been quite busy at night.
Not only did he meet up with Max to research making cupcakes, Wanda had also arranged to go out with Big Dipper at night.
The little witch had a good reason.
Since Big Dipper had suggested that she go out more often to experience the world, it was best for him to accompany her during this period of adaptation, or she might lose control when beating up hoodlums at night.
Thinking of a certain 'person' who wasn't human, Luke finally took the time to invest more in the little witch to avoid being 'stabbed in the back' again.
On the other side, he had to deal with Skye's advances. Even Selina sensed that something was wrong.
