After witnessing Luke's (Anthony Geary) personality switch the literal minute his past with his sister, Patricia (Dee Wallace), was brought up, Tracy (Jane Elliott) and Lulu (Emmee Rylan) have been on a mission to find the missing sibling on General Hospital.

Dee Wallace Joins 'GH'

Now, after Spinelli's (Bradford Anderson) research turned up an address, the two are ready to see if they can find out what answers she may hold that can explain what exactly has happened with Luke in the past year-but when they arrive at the address that was known as her last one, they will encounter someone else-her daughter, and could wind up at a dead end if they aren't allowed to speak with Patricia herself.

"Why are you so interested in my mother?" she asks them in a preview clip for the Friday, March 20 episode.

Luke's Family Seeks Answers

Lulu and Tracy may be forced to spill the whole story as a result-but it could be what they need to get access to the woman they seek.

Patricia may be willing to give them answers if she learns just hos Luke has changed, and how bad it has gotten. Not only has he tried scheming to find ways to take over Port Charles by becoming the previous head of the Jerome crime family, but he also arranged for Jake (Billy Miller) to plant a bomb aboard the Haunted Star-with the intent of killing Lulu and Tracy as well as everyone else.

Since then, he has also been sent to Shady Brook after he attacked Scott (Kin Shriner) and bit off a portion of his ear-but also escaped from the facility and hasn't been seen since. In fact, if he realizes his wife and daughter have put together the pieces to his secretive past, Patricia could be in danger if he finds her first.

General Hospital airs Monday-Friday at 3 p.m. on ABC.
