Will (James Atherton) is to reveal the affair with brother Dodger's girlfriend Texas (Bianca Hendrickse-Spendlove) in January, but will tell an elaborate lie in order to win back favour from his family and friends, according to Inside Soap.
"Hollyoaks fans will be shocked to the core by Will's behaviour," a soap source said.
"His plan is reckless, and life for Texas may never be the same."
Texas left Chester for America just before Christmas in order to get over the guilt of her one-night stand, and will unexpectedly return in early January.
Savage eventually confesses to the affair publicly during a speech at his father Dirk's engagement party with Myra McQueen.
Hollyoaks airs today (December 28) at 5.25pm on Channel 4.
