EMMERDALE fans think they have worked out a shocking paternity twist after Lewis Barton made his soap debut.

Netflix actor Bradley Riches made his first appearance on the ITV programme last night as the long-lost brother of Ross Barton.

Ross and his aunt Moira were left shocked to discover that there was another member of the family in Lewis.

Lewis’ mum is Emma Barton – meaning he is the half-brother of Ross, Pete and the dead Finn.

It appeared to transpire that Emma gave birth to Lewis during time apart from husband James Barton when they split and soon had him adopted.

The rest of the Barton clan had no clue about Lewis’ existence until he sent a letter to the family at Butler’s Farm.

Ross and Lewis later agreed to meet but soon, Ross decided that he wasn’t interested in building a connection and left Lewis hanging.

However, fans think there is another twist in the tale still to come.

In a mind-blowing DNA twist, some Emmerdale viewers have speculated that Cain Dingle could be the father of Lewis.

As fans passed their theories on who it could be, one suggested: “Cain I bet.”

Someone else echoed this, as they wrote: “He could pass as Cain’s son.”

Suspicion continued as another wrote: “I suspect there might be a twist so maybe.”

Actor Bradley – who also appeared on Celebrity Big Brother last year – recently revealed how he got the role on Emmerdale.

He bumped into a producer from the soap at the National Television Awards and got chatting.

And while originally he auditioned for the role of Dylan, April Windsor’s homeless pal, instead he was offered the role of Lewis.
