They've built Denny into such a partner of Alan's that it would be hard for him to leave or even majorly cut back, without making the charactor very sick or dead at this point.
Maybe it's just because I'd just seen her Designing Women co-actress on DH, but I swear the woman tackling Denny looked like a shorter version of Delta Burke, except there was something lopsided about her face. Same 80's hair, etc. Or is it her after some kind of plastic surgery? Am I losing it?
