This evening saw the first eviction of the series with Marco facing the axe alongside Andy West, Georgina Leigh Cantwell and Emma Jensen.
Marco got the boot out of the four after receiving the most votes to be evicted from the public.
Speaking after his exit, Marco reacted: "I was a bit surprised, but I was ready to go, if it happens, it happens. I don't take it personally."
After watching back to the nominations, Marco confessed he was shocked to have been voted for by Sam Giffen although expected the votes from both Lateysha Grace and Georgina.
Emma then moved on to quiz Marco on the elephant in the room: His relationship with Laura Carter.
Marco said there was an instant and genuine attraction with Laura saying: "You've just to lose yourself in there and go crazy."
However he admitted: "I should have definitely taken my time but who knows? I don't regret anything I do."
Emma then delivered a blow to Marco by revealing his fiancée Kim Melville-Smith wasn't present.
"She [Kim] told me I had a hall pass and it was an open relationship in the house, we had this discussion," Marco said.
He went on to back Emma or Jason to win the series.
