What would happen to Vincent if Mia had died?

When Mia overdoses from her Cocaine use and Vincent panics, what would have happened if Jimmy had either not been home to help them out or if he had refused to help and Mia had ended up dying?

Or if they had tried to save her life but she had still died anyway? Would Marcellous Wallace have been understanding or would Vincent have suffered an untimely end?

I would love to see how Jules would have handled Mia overdosing on drugs though, because he was a lot more cool and street smart and did things differently than Vincent did, he might have called The Wolf and gotten help from him.

Also Vincent could have called 911 and reported Mia's drug overdose to them and allowed them to take her and save her life, then she is released and promises not to tell Marcellous about what happened, dont know why Vincent never considered calling 911 at Jimmy's house at all.
