I don't think Lee will kill himself. I think he will go into meltdown and be found cowering in the gutter somewhere and admit all to Mick about the extent of his debt and the robbery, Whit will leave him and abort the baby, and Mick will bite his tongue and have to pick up the pieces (with the assistance of Johnny of course).
I can't get my head around Michelle with red hair. Sorry.
I'm counting the days to Roxy and Ronnie leaving however. Fed up with the same storylines over and over.
