The former army boy - played by Mikey North - opened up to new-girl-on-the-block Nicola Rubinstein (Nicola Thorp) about his traumatising trip to Ukraine - something he's been hiding from his partner - last week over an alcoholic beverage.

But it looks like things will end in disaster for the flame-haired hunk as he will fall into the arms of the brunette beauty later this week after Sarah (Tina O'Brien) presses him for answers about his new job, which sees him putting his life at risk for his employer.

Mikey said: "Nicola is the only person who he's told exactly what happened in Ukraine and what he had to do. That secret is one of the reason he feels an attachment to her Nicola is there at the right time, and in the heat of the moment Gary isn't thinking.

"... The truth is that the PTSD from when he was in Afghanistan is rearing its head, and Gary is very volatile. The pressures from this work are bringing a lot of demons back."

And it's not just Sarah who starts to pick up on Gary's bizarre behaviour as he will snap at his friends Kirk Sutherland (Andrew Whyment) and Tyrone Dobbs (Alan Halsall).

He said: "He's on edge the whole time and then he snaps at Tyrone and Kirk for no reason. Sarah tells him to calm down but he flies off the handle and goes outside.

"She follows him to see what's wrong and Gary really loses it, trashing the area and shouting at Sarah before storming off. After that Nicola finds him in the ginnel."

And, although Gary deeply loves Sarah, the booze clouds his judgement.

He explained to Inside Soap magazine: "It's a tricky one, because Gary does love Sarah and they are so good together. But Gary's judgement is clouded by drink. He's just had an argument with Sarah and is not thinking straight. This isn't the Gary who was around before he went to Ukraine - this is someone else. He's gone crazy."
