i was wondering this myself, and being impatient as i usually am, i flicked through the days of next week on my sky tv guide, and mondays (tomorrow) says (i have put these in white incase i spoilt it for anyone... so just highlight below to read)
Ronnie is devestated at being denied her chance to say goodbye to her son
and tuesdays (inwhite also)
It is baby tommys funeral, and as kat and alfie bid farewell to their son, a devestated ronnie interrupts the wake with a shocking announcement?
could that be it
