The story twist occurs as Chris and some of the other Erinsborough locals take part in a charity camp-out, which has been organised by Scotty's girlfriend Georgia Brooks to raise money for the hospital.
As Chris gets settled in his tent, he is surprised when Scotty (Rhys Uhlich) decides to pay him a visit. Chris is then left totally flummoxed when Scotty says something that could be construed as making a move on him.
James Mason, who plays Chris, commented: "There is definitely a serious side to this storyline because everyone thinks this guy Scotty is straight, including his girlfriend.
"However, there are some funny moments as well with Chris Milligan [as Kyle Canning] leading up to the big revelation, which were great to play."
The latest twist in Chris's personal life comes after he recently split from Aidan Foster, played by Bob Morley.
Mason laughed: "Yes, nothing like a break-up to kick start the year. I definitely miss Bob - we played opposite each other on and off for 18 months so started to finish each other's sentences."
Chris's new storyline with Scotty begins next week in Australia and from April 4 on Channel 5 in the UK.
