Must re-watch 'Redrum' episode. I forgot to metion this earlier but I watched 'Overlaod'on Spike. And something Greggo said when Cath and Nick were talking to Greg about some results. "When it's important to Nick I push further." It made me think he was trying to impress Nicky. And even though supposingly Cath is the only one to know about the aweful thing that happened to sweet Nicky *hugs Nicky* I wonder if it was more of "crush" stage at the point bewtween the 2 of them that Greg knew as well. Weather or not Greggo figured it out(general idea not specifically what was told to Cath) or Nick told him.
