After months of prison visits and family drama, Kat and Phil finally have reason to celebrate as their dream wedding day arrives.

But not everyone is as thrilled about their impending nuptials and the couple's excitement is short-lived when Kat's ex Alfie makes a surprise return to Walford with one thing on his mind getting Kat back!

Kat's shocked to see Alfie on the eve of her wedding to Phil, and when he gets down on bended knee and begs her not to go through with the wedding, she gives him short shrift.
