I guess so. He would have been useful looking for Erik, but I guess Jake and Marco did a good enough job. I thought Ax was funny. He got obsessed with TV, then he probably watched that episode where they talked about how much TV you should let your kids watch, then decided to tone down the TV watching.
then he picked up something else in Cassie's barn, and said how much he missed it. So it's back to old obsessions? Gotta love Ax-Man.
