Not a text. Not a single phone call after last week. You're not gonna answer. How about I answer it for you, Billy? You told me that I needed to take care of a slump buster, huh? I went out there and busted that slump, and I busted Max Caster’s face doing everything, everything that you taught me to do, and you weren't there again. You put your hands on me, and you should have been there punching Caster’s face with me. So let me ask you this, like I’ve been asking you every week. Where were you because you were not there for me, clearly.”A breakup has been teased, and it will be interesting to see what will happen in the near future.
