EastEnders introduced newcomer Leo to the show on Tuesday, and fans are very confused.
Bianca Jackson was seen looking very worried in the latest episode of the BBC soap, after coming face-to-face with the mystery character.
While little was said about him that would reveal their link to one another, fans were left speculating over why he was at Whitney and Callum's wedding.
The credits for the latest episode revealed the character is named Leo, and is played by actor Tom Wells.
He made his debut on the soap as he was speaking to Bianca's teenage daughter Tiffany Butcher.
Whitney had just fled her wedding to Callum, while their loved ones remained at the venue.
But as Bianca went to get Tiff to head back to Walford, she come across the pair laughing together.
Clearly worried for her daughter, she warned the stranger that it was a family wedding.
He then claimed to also be attending a wedding that day, while Tiffany was confused by the moment.
As the two characters were left alone, Bianca gave him a look as though they were hiding something, with it clear they knew each other.
Her expression made it clear she wasn't going to have him near her family, while his own look was one of a warning.
So who is Leo and how does he know Bianca, and could it be tied in with her bombshell the episode before?
Bianca had told pal Kat Moon that she's just got out of prison, while she hasn't explained why she was there.
EastEnders airs Mondays and Fridays at 8pm, and Tuesdays and Thursdays at 7:30pm on BBC One.
