EastEnders fans are convinced they have worked out who is blackmailing Vicki Fowler and Zack Hudson after they were caught kissing in an alleyway
EastEnders viewers are certain a familiar character will be revealed as Vicki Fowler and Zack Hudson’s blackmailer.
The duo were snapped snogging in an alleyway by a mysterious person and whoever captured the covert photograph is now demanding cash in exchange for keeping quiet.
Soon-to-be bride Vicki (Alice Haig) was attempting to enjoy her hen party when her sister Sharon Watts’ (Letitia Dean) half-brother Zack (James Farrar) appeared as the stripper.
Spotting their chemistry, Kathy Beale (Gillian Taylforth) triggered the fire alarm to prevent them getting any closer but she only made matters worse as once isolated in an alleyway, Vicki and Zack began snogging.
The episode concluded with an unknown person clutching a mobile showing a photo of the pair kissing and viewers have flocked to social media to voice their predictions, reports OK!.

While some believe it might be Kathy, others reckon Sharon could have returned to Walford but most fans are certain Vicki’s former boyfriend Spencer Moon, portrayed by Christopher Parker, might be back after 21 years.
Supporters will recall that Alfie Moon’s sibling was romantically involved with Vicki for years but the couple broke up after she betrayed him with her fiancé Ross Marshall (Alex Walkinshaw).
Although there’s been no official word that Spencer is returning to Albert Square, some people are adamant he could be seeking vengeance on former girlfriend Vicki and one-time best friend Ross.
Taking to social media, one fan wrote: “I think it is Spencer he is coming back.” Another contributed: “I reckon it’s Spencer.”

Someone else commented: “What if the person who caught Vicki and Zack is Spencer?” A fourth shared: “That looks like a man’s jacket and gloves. Maybe Spencer #Eastenders.”
In forthcoming episodes, EastEnders spoilers have disclosed that Vicki becomes frantic as she and Zack try to locate their mysterious blackmailer and begins to suspect it’s Zoe Slater (Michelle Ryan).
Vicki eventually confides in brother Mark Fowler and he succeeds in tracing the phone.
A bewildered Vicki becomes wary of Ian Beale (Adam Woodyatt) when he remarks about Vicki and Zack’s bond, and she goes to challenge him with Zack and Mark spearheading the group’s journey to No.25.

Ian is stunned to learn that Vicki has been conducting an affair with Zack, and Kathy was aware of it, and he urges Vicki to be honest with Ross.
Nevertheless, the difficulties are nowhere near finished for the duo as the blackmailer subsequently demands £20,000 in exchange for their silence.
Vicki concludes she has no alternatives left and informs Zack she intends to disclose everything to Ross. Will she be truthful or will the blackmailer expose the details to Ross first?
