I wish he wasn't. I like Rob. Not too bothered about Peter leaving, he is past his sell by date.
Plus Rob manages to make Tracy a bit more bearable.
After two-years he is leaving, but will not doubt be replaced by these new "bad boy" characters. The cycle starts all over again. Rob has been great recently, and Marc Baylis has been improving in the role. Tina should just of fallen from the roof and died, and Rob should of been temporary written out (if he is arrested at all). It was too far making him savagely attack her.
