EastEnders - Martin confronts Pauline & Derek over Mark's death (16th April 2004) 

Martin is angered as he discovers that Pauline and Derek were aware that Mark was dying, but didn't tell him.
Unfortunately I had to scrap the end of this video where they return to Walford as it got picked up for copy right issues.
