As I recall they were in the first episode back of the new series, but didn't see them last night, I doubt very much that the producers would just cut them out, it would be all wrong seems as how everyone, as you did, would notice perhaps their presence is not needed in the story at the moment. It occurs alot in some of the soaps sometimes you won't see a particular character for weeks and then they'll appear again,it's just how the storylines work out.
I was wondering what had happened to them last nite too.They were definately in the first episode cos I remember them making loads of mess and their Dad was letting them get on with it cos he stays at home now while Lynette works.Like
Emma-J says its that sort of programme,people disappear and then appear again.Nice to see John(gardener) again last nite.Mmmmmmmmmm
I think the twins are the oldest and probably at school. The boy last night was younger, just starting playgroup and we have previously seen the twins in a classroom.
