Only one of them knows the truth about their past, but that won't keep things from possibly progressing further between Liam (Scott Clifton) and Quinn (Rena Sofer) on The Bold and the Beautiful.

Steffy & Wyatt Shocked By Liam's Message

Liam has been suffering from amnesia ever since he fell in the Forrester parking lot, and Quinn has been keeping him in her cabin in Topanga ever since. She has also lied to him about his past, telling him he is Adam, she is Eve, and they are married, to try and encourage Steffy (Jacqueline MacInnes Wood) to accept that Liam has left her for good so that she would move on with Wyatt. However, in the process, things have seemingly progressed for "Adam" and "Eve" as well, with some romantic embraces and gestures--and they could grow even more.

Despite believing he is married to her, "Adam" will tell his "wife" that he's frustrated by the fact that he doesn't remember anything about their past, prompting Quinn to tell him whatever she can without giving away anything that might trigger his real memories.

Quinn Deals With Steffy's Need To Hear From Liam

"It's really frustrating not knowing who I am, who we are, how we got to this point," he says in a preview clip for the Friday, Feb. 12 episode.

"What do you want to know?" Quinn asks.

However, when he continues to express his frustration, Quinn will get close to him again, assuring him that he doesn't need to know anything more--which could lead to the two taking another step in their romance.

"I am all you'll ever need," she says in the clip.

The Bold and the Beautiful airs Monday-Friday at 1:30 p.m. on CBS.
