Another source of comedy, though tinged with sadness, is Nash's father Nick, afflicted with Alzheimer's Disease. Nick, like his son Nash, is cagey with women. Charlotte is left standing at the altar - the same Charlotte who broke her hip last season because of vigorous sex with Nick. Poor Charlotte takes a lot of abuse from ole Nick, though none of it seems to be Nick's fault. Nick can't help her brittle bones, Nick can't control his Alzheimer's, etc.
Women fail men, so men have to take care of men.
Speaking of women, Nash finds a new romantic interest, only to have his job get in the way of romance. Nash finds he has to lie to Dana Traner to get close to her - real close. Dana's former boyfriend shows up, taking her hostage. A big shoot-out ensues with the boyfriend hurling lots of lead at Nash. Nash, being her current lover, having to shoot her boyfriend - very messy.
