Are there any characters you regret killing off?

I think Charlotte was killed prematurely. I felt there was a lot more to get out of that character and I felt that Stephanie Chavez-Jacobsen did an excellent job playing her. I can't quite remember why the decision was taken at the time to lose her. I must be getting old - my memory is not what it was :-) I also thought it was a shame to lose Ken, Hayley, Nick and Will's father. Unfortunately the actor wanted to leave. I felt he could have settled in to being a regular in the Bay. Thankfully he's agreed over time to come back and do a number of very effective guest appearances as Ken's ghost. The actor is a successful theatre actor and has performed in a lot of plays since leaving the show.
