Son of a freeloader! Now I wonder if the REAL baby daddy is involved in this? Maybe he showed up and was arguing with Lana when Mayson came back, heard the fight, and charged in thinking that Lana was fighting with Clark. Before she could explain who she was and why she was there, the guy killed her (maybe not on purpose, but she's still dead) and dragged Lana away with him. Or, maybe Mystery Baby Daddy did recognize Mayson and that's why he whacked her. How am I doing?
Or maybe I've been reading too many mystery novels.
