The actress, who joined the village serial last October, believes that the pair have the potential to turn their romance into a long-lasting relationship.
''They're a bit commitment-phobic, but they fancy each other and they're sexually compatible," she admitted to Inside Soap.
"Each of them is trying hard not to let the other one know that they care. I think they've genuinely fallen for one another, but won't let on," the star added.
Carl actor Tom Lister previously suggested his alter ego's link with Megan will last for some time, but insisted any relationship would be turbulent.
Faye recently revealed that she is expecting "a real thrill" for Emmerdale's 40th-anniversary live episode later this year.
