Stacey Slater (Lacey Turner) has been left horrified by a terrifying stalker in EastEnders, completely oblivious to the fact that it is actually family friend Theo Hawthorne (William Ellis).

Theo wormed his way into the Slater household under the guise of tutoring pregnant child Lily (Lillia Turner), with Stacey unaware of the fact that he was the anonymous client she had been video calling.

He has since stepped up his behaviour to a worrying level, sending Stacey gifts which make it clear that her stalker knows where she lives.

However, with Stacey still unaware of his identity, she is of the belief that Theo is a friend who has her best interests at heart. Because of this, she is set to accept a drink with him in upcoming episodes.

Theo arranges what he views as a date in order to take Stacey’s mind off her upcoming viability hearing, but his delusions are ruffled when Eve Unwin (Heather Peace) tags along for the event.

The next day, Stacey and Eve have a disagreement over Eve’s upcoming date with Amanda, with Stacey insisting that she should stop ignoring Amanda’s calls.

Defensive Eve claps back by demanding that Stacey stop leading Theo on.

Having been given food for thought, Stacey later speaks to Theo about there relationship, making it clear that they are nothing more than friends.

Theo clearly takes the news badly, as it isn’t long before Stacey receives another letter from her stalker.

Eve is determined to cancel her date with Amanda in order to be there for Stacey, who is clearly spooked by the letter, but she insists that she go, even lending her an outfit to wear.

With Eve gone, will Stacey be safe?
