Speaking to Metro.co.uk at the NTAs, Shona explained the storyline will continue to “get darker” as Leo’s days could be numbered.
She told the publication: “Whitney is in a lot of danger it’s only going to get darker it’s going to be good.
“I loved every minute working with Tom Wells, I think he’s an amazing actor he can just snap into that psycho stalker mode quite easily.
“There is a light at the end of the tunnel but it’s a long tunnel but she will be alright, she will be fine,” added Shona.
Will Leo make it out alive or could he finally get his comeuppance for his behaviour?
EastEnders continues tomorrow at 7.30pm on BBC One.
