Jess and Pete had been on a few dates, but both recently admitting they were confused about what exactly was going on.
During Sunday night's episode (8 November) however, they revealed in separate conversations that things had been going really well between them.
That all changed when Lewis dropped a bombshell to Pete about Jess, revealing he had kissed her a few weeks ago after her vineyard date with Pete.
A furious Pete blasted Lewis and Jess a "f**king joke", while Lewis has since apologised, having recently admitted the kiss "wasn't really anything sinister".
Giving his take on Pete and Lewis' showdown, Jake said: "Lewis was snogging Jess, but Pete was trying to crack on with Jess. A bit awkward because obviously they're two friends. I don't know, could there be a tear up?
"The problem is with Lewis not telling him is like what's happened in the past with me, if you don't come out with the truth, it bites you in the little arse. Obviously, Pete's going to be a bit annoyed because he's trying to crack on with her."
However, Jake thinks it may not be completely over for Pete and Jess.
"It's a drunken kiss, hopefully Jess can explain to him the reasons," continued Jake. "If it was a drunken kiss, it was a drunken kiss and I'd like to see Jess and Pete have a go at it, I think they suit. They both have long hair!"
In fact, after last night's episode, Pete hinted that he has forgiven Jess for kissing Lewis when he tweeted: "Nobody is perfect, we all make mistakes..."
While Lewis has spoken out about the bombshell, Jess is yet to give her side of the story.
