Jim is now saying 'Is it about Frank Carson's Dressing Room' - so something happened there that Linda's upset about - and Frank Carson was before Jim's heyday - but as he's dead, Jim shouldn't have brought his name up , very nasty, don't know why he did that ,- can only think that Linda pressed some buttons with him , so he threw it back at her bringing up something that would really get to her ! and boy didn't it.
Oh dear, think Jim's blown it, for himself....he was doing so well keeping stum with Linda's verbal prodding. But he's kicked her down now, not good for Jim.
