i thought that carol had found out about nicki and david secretly and poisoned him or something, hence the heart attack. I know it sounds dark but did anyone get a similar vibe. its just how she seemed in the car.,,,.seemed odd. it thought it was maybe another 'twist'

Utter nonsense.

So are you!

Charming as ever Rad.

so I guess you all know each other on here...

Yes. In answer to your question no it felt to me that she was thinking I've been let down again. David was always a cad in his dealings with Carol.

I just think she didn't know what to think

She was a bit harsh with him in the hospital imo...
