Ok, I think I have worked out what Max Branning's Manchester secret is. When he went to that house, he seemed to be considering whether or not to knock on the door, before putting money through the door. I think he might have got a woman pregnant. The money could be for child support, and maybe he wanted to go into the house to see the child. I also think the woman could be who he has been in contact with, instead of him beings Kat's mystery man.
