Here's how Home and Away's Theo and Lacey are caught out by Gage

A worrying development.

Home and Away's Theo Poulos makes a potentially deadly mistake next week as he gets caught kissing Lacey Miller out in public.

Dangerous gang leader Gage Reynolds is furious when he spots Theo and Lacey in a passionate embrace – and his thoughts immediately turn to revenge.

Shortly before Gage's big discovery, Theo shows off his finished car after spending weeks working on it at the garage.

Gage is impressed, but makes it clear that he now wants to buy it from Theo to use in his illegal street racing.

While Theo is keen to drive the vehicle in Gage's next race, he stands up to the ruthless River Boy by insisting that the car is not for sale…

"Gage is used to always having things his own way," our Home and Away source explains.

"He was happy to have Theo take part in one of his recent races, but only if Theo was using one of the River Boys' cars and not his own. Gage takes a bigger cut from any winnings that way.

"It's clear that Theo knows his own mind and he's more than willing to stand firm where Gage is concerned."

During drinks at Salt, Gage continues to put pressure on Theo to sell. He simmers with rage as Theo turns down several generous payment offers.

Lacey is present for the tense discussions and her feet touch with Theo's, right under Gage's nose. The secret lovers seem to be playing with fire as their affair continues.

Later, Theo invites Lacey into his car and they get intimate together.

Gage spots them together and he rages over Lacey and Theo's betrayal.
