Does Michael know Ronnie? I cant remember

yeah..

She took his son so yeah..

Yep.
He even manipulated a situation on the day of her court appearance that she would be left holding Tommy.

Yes, he was dating Roxy at the time but became obsessed with Ronnie. He slept in her bed (pretending to sleepwalk), made a pass at her and gave her perfume to Roxy

Yes I remember now. Thanks all x
