As if EastEnders wasn’t throwing enough twists at us with the shock revelation that Vincent Hubbard works for the police, there’s another surprise on the way.

It’s the day of Vincent’s birthday party and wife Kim (Tameka Empson) has dressed up in a sexy Santa suit.

But she’s caught off guard by the return of niece Libby Fox.

Libby (Belinda Owusu) was last seen in the Square in August celebrating her birthday party when she received a call from sister Chelsea.

Going outside to answer, fans discovered that Libby was hiding a big secret from mum Denise (Diane Parish).

We watched her leave the Square for Oxford with the mystery news weighing heavy on her shoulders, so the question is – why has Libby returned and what message has she got to tell?
