The truth about Luke (Anthony Geary) and Bobbie's (Jacklyn Zeman) older sister Patricia has been revealed, but the news that she is alive and in a convalescent home will cause Bobbie and Tracy (Jane Elliot) to make an alarming discovery on General Hospital.

Lulu & Dante Race To Save Valerie

After Tracy broke the news to Bobbie that her sister was dead, as per what Valerie (Brytni Sarpi) said, the two women did some digging and realized she had lied-and that Patricia was at Oak Hill. Desperate for answers about what caused Luke's psychotic breakdown, the two headed there, only to run into a gun-toting Luke in Patricia's room.

Now, Luke will unveil his sister to his wife and other sibling for the first time-and his getting to the home before them could prove to have kept Patricia from being able to say anything.

Lulu & Tracy Seek Answers About Luke

"Ta Da!!" he says in a preview clip for the Monday, March 30 episode, as he pulls back a curtain for them to see what he's hiding.

Meanwhile, Valerie is worrying about what could happen to her mother now that Luke knows she is alive, and where she is, especially after he attacked her, his own niece, without caring if he truly left her for dead.

Now, with Dante (Dominic Zamprogna) and Lulu (Emmee Rylan) at her apartment trying to comfort her, Valerie will express her worst fears about the current situation.

"Your psycho father must be at Oak Hill," she says in the clip.

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