On the latest episode of EastEnders, Jack Branning and Rainie Cross were seen sharing a steamy kiss before seemingly taking things further.
The pair’s illicit actions were behind the back of Jack’s brother Max Branning, who is currently married to Rainie.
The duo announced their shock marriage earlier this year, with it later being revealed that it was a sham, however the two have recently developed genuine feelings for each other.
On Thursday night’s episode, Tanya and Jack were seen getting close as Tanya Frank’s character attempted to cheer up her brother in law after his split from Mel Owen.
The duo headed out for a drink with Max but after Jack confided in him that he wanted a marriage like him, Max revealed the truth and told his brother that he and Rainie are not really in love.
When word got back to Rainie, she was left devastated as she has made no secret of her true feelings for Max.
As Jack comforted Rainie the pair shared a kiss, and though Jack initially walked away, he later returned and things got very steamy between the pair as the episodes ended.
Rushing to social media after the scenes aired on the BBC soap, fans admitted they couldn’t believe the pair would betray Max in this way.
Taking to Twitter, one posted: “I’m sorry did that just happen? Jack and Rainie?! I’ll bet Max gets feelings right when it’s too late. #EastEnders.”
While another questioned: “How many women have Max and Jack shared now?”
“NO NO NO NO NOOOOOOOOO JACK AND RAINIE NO! #EastEnders @bbceastenders,” added a third.
EastEnders continues on BBC One.
