But what could it be?
Well, Inside Soap tease the storyline by saying that Mary's bombshell leaves Norris speechless. We already know, in the previews already released by ITV for next week, that Mary faces a breast cancer scare.
This forces Mary to think about her own mortality and she starts work on a bucket list. In typical Mary style, the list is inside a ring binder. And it's a ring binder that Erica finds and she can't resist peeking inside. Erica tells Norris what she's found out about Mary and Norris tries to help Mary.
However, Inside Soap say that nothing can prepare Norris for what he's about to hear as Mary spills her deepest, darkest secret to him.
