Preview pictures for the episode show Harry with his suitcase outside the Marbs villa as he prepares to jet back to Essex.
Last week's series opener saw a blissfully happy Bobby and Harry enjoying their time together in the Spanish sunshine – until Bobby found out from mutual friend Gemma Collins that Harry had been in Tenerife at the same time as an ex-boyfriend.
Bobby became paranoid that something happened between Harry and his ex, but Harry insisted it was just dinner and nothing else.
Then, in an explosive scene at the end of the episode, previewing tonight's action, we saw Harry confessing he DID sleep with his ex.
On tonight's episode we'll see what happened next – and a heated exchange between Gemma and Harry as he leaves Marbs.
We already knew that Harry would leave early, as a source told Reveal during filming: "Things are looking a bit rocky for Bobby and Harry, as they've been rowing a lot in Marbella. Harry is even flying home early, which has left everyone wondering whether they are even still a couple."
Bobby then told us: "We began dating six months previous to him filming for the show. It was just the next natural step because I'm on a reality TV show, so it made sense for the part of my life to also be on the show.
"The first few days were absolutely fine, but before we were going, people were talking to me and saying, 'Are you worried about the TOWIE curse?' We met off the show and we've been together for six months and I thought the gays would beat the curse. But quite early on into the trip stuff happened and things just didn't turn out how they should be. I never expected to be flying home on a separate flight to him."
TOWIE airs Wednesdays and Sundays at 10pm on ITV2.
