Ben Mitchell crossed a line in Monday's episode as he cruelly used the death of Zack Hudson's baby daughter against him and EastEnders fans suspect this could be the beginning of a dangerous path for the Mitchell bad boy.
Zack ( James Farrar ) was forced to pull out of a charity boxing match with Ben ( Max Bowden ) after being diagnosed with HIV, with Martin Fowler ( James Bye ) taking his place.
Despite winning the fight, Ben couldn't resist sticking the knife in further, while in the Queen Vic, resulting in Zack jumping in to defend his friend.
