This is a terrible joke and I love it so much. Also, this storyline’s over! Random one-offs for next little while. Also, I’m moving, so things may get intermittent. Gonna do my best to keep the schedule on track, but forgive me if things get too hectic. 
Seems like Billy is running a deficit of one digit.
