Their encounter in an elevator could wind up changing both Franco (Roger Howarth) and Nina's (Michelle Stafford) lives forever on General Hospital.

Sam and Patrick Investigate Nina

While stuck in the elevator, Nina had spilled to Franco that she saw his girlfriend, Carly (Laura Wright) kissing her ex, Sonny (Maurice Bernard)-which caused Franco to have a dangerous meltdown. In an effort to calm him down, Nina got up from her wheelchair-revealing the truth the Franco that she actually wasn't paralyzed.

Now that they are free, she may consider telling Silas (Michael Easton) the truth about her disability-before Franco does it for her.

Sonny Warns Franco That His 'Days Are Numbered'

"I've been lying to you," she says to Silas in a preview clip for the Tuesday, August 19 episode.

Meanwhile, Franco wants to confront both Carly and Sonny, for breaking their promises that they would stay away from one another-but when he arrives home to talk to Carly, he could be in for a big shock.

"Honey, I'm home," he calls out in the clip.

However, in the bedroom, Carly and Sonny are mid-makeout. Sonny's shirt is gone, and he is busy ripping Carly's off of her. The two finally began giving into their chemistry while Franco was stuck in the elevator, after Sonny confronted Carly about her relationship, and taunted her with an insult that the only reason she was with Franco was because everyone told her not to be.

As a result, Carly ran to Sonny and gave in to her conflicted feelings-but the move could cost her Franco if he walks into the bedroom now.

General Hospital airs Monday-Friday at 2 p.m. on ABC.
