Photo Spoiler: Wedding day blues

On the morning of his wedding, Kat arrives to pick up Tommy, and to talk to Alfie after their smooch. Alfie tells Kat it was a mistake, and she did the right thing by stopping it... which breaks poor Kat's heart.

Kat decides that she needs to leave Walford, and gets Tommy ready to go to the airport. Bianca bumps into the pair en route, and insists that she'll drive Kat to the airport...

In a church across town, Alfie stall the proceedings as he panics. He finally confesses the truth about his kiss with Kat to Ian, but Ian persuades Alfie that Roxy is the right woman for him (but, come on, would you take romantic advice from Ian Beale?)

When the big moment finally arrives, Roxy is relieved to see Alfie standing at the alter, and she steps forward to become the next Mrs Moon!

While Kat thinks she's on the way to the airport in the back of Terry's cab, Bianca actually ends up driving her to Alfie and Roxy's wedding instead. Is she going to object?

Later in the week, we all wish Dexter a Happy 21st Birthday! He makes a lovely birthday speech, telling everyone how thankful he is to have Sam back in his life... It all becomes too much for Sam, and that familiar, claustrophobic feeling creeps up on him again!

Lola decides to invite newvbie Dean to Dexter's party in a bid to make Peter jealous... and it seems like it's working, Peter does not look impressed.

But tensions boil over completley when Dean implies that Lola is easy... Peter snaps and punches him.

It's all kicking off on The Square! Make sure you don't miss it!
