Izzy should really take herself off Denny's case... although that would be a major "step" in their relationship...a "we're not just joking around" step. And of course she couldn't justify spending time with him during her workday then.
I seem to recall he was only signed for a limited additional series of episodes... does anyone recall how many? Of course he was only supposed to be on for one episode originally and he got his "life" extended once, so maybe, cross my fingers, he will again. I fear not though, we seem to be heading towards a major crisis.
Remember when he went into earlier risky surgery? There was something about a letter for his lawyer... maybe he has left Izzy his fortune---big improvement over the trailer park life for her.
Would miss his charactor... they write such cute flirting for them.
