I know that Little Mo discovers she is pregnant by Alfie but i heard that Kat also becomes pregnant but doesn't tell him.
I really would like to see a happy ending for Alfie and Kat, i think Little Mo having another baby that isn't Billy would rule out a reunion for them.
I got this from another spoilerboard so i don't how true it is. I hope Little Mo's pregnancy is a false or that it is Billys maybe she has one night stand with Billy. I thought after the rape Little Mo didn't want to sleep with anyone (i thought she said this to Alfie) and now she is running into bed with Alfie and getting pregnant.
