Last year when David was trying to make amends, he gave Bianca an envelope full of cash in the Vic. It was a substantial amount of money, at least a few thousand judging by the size of the envelope.
Wonder how Bianca spent it so quickly? (I think she might have given some of it to Terry to fix his cab but she didn't give it all away).
Carol could always sell her wedding ring/dress since they are so strapped for cash.
I really hate these Bianca having no money stories!
