Thought EastEnders may have a quiet week after all of the recent drama? Of course not. Tonight, Kush has a heart attack on the square following an argument with Denise. We would normally say he will probably be fine but given that he is currently about to take to the dancefloor on Strictly, we are less hopeful. Also tonight, Bernadette is devastated by Karen's actions, and a worrying truth comes to light, leaving someone in turmoil.
