Fabrizio Santino starred in Hollyoaks before making his Walford debut

EastEnders’ Zack Hudson (played by James Farrar) thought he saw a ghost from his past in the form of Brett Nelson (Fabrizio Santino) in Monday’s night episode. He then came face to face with Brett and he revealed a disturbing truth that could change Zack’s life forever. Express.co.uk explains exactly where you have seen Fabrizio Santino before.

Zack first sees Brett from the corner of his eye when he walks through the market.

The chef doesn’t know if he was just seeing things until he sees Brett again at Sharon Watts’ (Letitia Dean) gym, interviewing for a personal trainer position.

Zack later tells his sister not to hire him as he used to be a drug dealer and he used to be one of his customers.

With Whitney Dean (Shona McGarty) now pregnant with his baby, it’s no wonder Zack doesn’t want him on the square.

As Zack and Brett once again crossed paths in the square, the former asked for a quiet word down the Queen Vic alleyway.

Brett apologised for showing up in Walford, stating that he had no idea that he was living in the area.

He went on to explain how he was HIV positive and, as Zack and used to share needles as they did drugs together, he could have it too.

But does Zack really have HIV and how will Whitney react to the revelation?
