Soap fans know that while Callum is planning to marry girlfriend Whitney, he is hiding the huge secret that he is in love with Ben.
But while oblivious bride-to-be Whitney continues to plan their big day, Callum is struggling to get Ben off his mind and focus on his future with Whit.
Next week, Callum's secret is almost exposed when Whitney finds his letters from his old army friend Chris.
Callum struggles to explain them and instead of using this as the moment to come clean to her about his past, he continues to keep his true feelings bottled up.
But Whitney knows there is something her future husband isn't telling her and struggles to get excited as her friends and family plan her hen night.
Thankfully a chat with Sonia is all it takes for Whitney to realise that Callum is the man for her, and she heads home to tell him that she doesn't mind what happened in his past, all she cares about is their future together.
But would she be so understanding if she knew Callum's lusting after Ben?
As Whitney and Callum get ready for their pre-wedding celebrations, an unsuspecting Mick invites Ben along to the stag.
But while Ben is thrilled by the prospect of spending more time with Callum, Stuart isn't happy.
With Stuart in the know about Callum and Ben, he's determined to stop him coming to the party and slopes off in a bad mood.
But when he returns later, Ben is nowhere to be found. With Ben missing, Callum is suspicious that his brother has been up to his old tricks, but what has Stuart done?
Callum's stag goes from bad to worse as Stuart's surprises for his brother cause the party to turn sour, and soon a drunk Halfway has had enough and escapes the bash and heads off to find Ben.
But once he finds him, the pressure becomes too much for the groom-to-be and he ends up lashing out.
Clearly Callum feels like he needs to come clean to Whitney before their wedding, because before long he arrives at her hen do with something to say.
Whit is thrilled when Callum gatecrashes, but her mood soon changes when her husband-to-be tells her he needs to speak to her alone.
Whitney realises that Callum has something big to say... but will he tell her the truth about Ben?
EastEnders airs Monday and Friday at 8pm and Tuesday and Thursday at 7.30pm on BBC One.
