I know this is just speculation but can you explain who Marty was and what she did? I have never watched OLTL so I am really curious if this is the way they may take Liz. I Thanks

Miscarriage and nervous breakdown
Marty and John finally get together, and she soon discovers that she is pregnant with John's child. However, Natalie's feelings for John resurface just as Marty and John begin to celebrate their baby. Tragedy strikes, however, when Marty suffers a miscarriage after being pushed down a flight of stairs by a mystery assailant, who is later revealed to be Eli Clarke. Shortly after, John leaves Marty for Natalie.
Several months later, Cole is led to believe that Eli Clarke has murdered Starr and their daughter Hope, which results in Cole shooting Eli, killing him. Marty tries to take the blame, but Natalie soon squanders that plan and Cole is sent to prison. It is discovered that Starr and Hope had escaped Eli, but then had been kidnapped by Hannah O'Connor, a troubled young woman whom Marty had taken in to keep the girl from being sent into foster care. Hannah had become obsessed with Cole and had kidnapped Starr in order to kill her so that she (Hannah) could have Cole all to herself, but James Ford managed to thwart her plans. Both shocked and furious that she had never noticed that Hannah wasn't getting any better, Marty disowns her, coldly informing Hannah that she is unfixable and that it was a mistake to ever trust her before she is dragged away by the police. Marty vows revenge against a now-pregnant Natalie, who claims the baby is John's. Meanwhile, Todd tricks Starr into signing a restraining order forbidding Marty any visitation to Hope, Marty's grandchild, leaving Marty even more devastated.
Marty becomes suspicious of Natalie's friendship with Jessica's fiance and John's friend, Brody Lovett and wonders if perhaps Natalie's unborn child is really Brody's--- not John's. Upon obtaining a copy of Natalie's amnioplasty results, which claim that Brody is the father of Natalie's child, Marty uses it as an opportunity to exact her revenge. She confronts Natalie and attempts to blackmail her into springing Cole from jail, threatening to tell John about the DNA test if she does not. However, after discovering that John has proposed to Natalie, Marty seemingly promises not to do so, but in fact plans to tell Jessica at the ceremony and have her inform John. To this end, she crashes the ceremony, but her plan derails when Jessica is rushed to the hospital due to pregnancy complications. In the ensuing argument between herself and Natalie, Marty falls and strikes her head.
Natalie subsequently takes Marty to the Buchanan lodge, holding her at gunpoint and planning to leave her stranded at the lodge with no way to get help, and also to ensure that Marty loses her job as a psychologist after informing the cops that Marty stole her medical records. However, when Natalie's water breaks before she can leave, Marty turns the tables on her, turning a deaf ear to Natalie's pleas and departing, leaving the laboring Natalie alone with no way to send for help.
However, Marty has a pang of conscience and returns to help Natalie give birth. John tracks her and Marty to the lodge and walks in moments after Natalie has given birth to a baby boy. When Marty holds Natalie's baby, she suffers a complete nervous breakdown, believing it to be her and John's baby. At the hospital, it becomes clear to all that Marty is completely insane, as she is convinced that it was Natalie and not Eli who pushed her down the stairs. After bursting in on John and Natalie, sobbing that the baby is hers and that Natalie is trying to steal it, Marty is committed and sedated.
The truth about Natalie's baby eventually comes out, and a betrayed John calls off their engagement. As he begins dating Kelly Cramer, a seemingly recovered Marty is released from St. Anne's; soon after, she confesses to her psychiatrist, Dr. Buhari, that she switched Natalie's paternity test results--- and that John is indeed the father of little Liam. However, instead of going to Natalie and John with the truth, Marty keeps it to herself in the hopes that she will be able to reconcile with John. Showing that she is still deranged, Marty threatens both Natalie and Kelly, prompting John to feign interest in a reconciliation with Marty just so he can keep an eye on her. In May 2011, Marty becomes even more unhinged and sees not only Natalie but Kelly as a threat to her reunion with John. When Marty arrives at John's to prepare him dinner, she has a confrontation with Kelly, who pick up a knife in defense. Off screen Marty stabs Kelly twice, who is later discovered bleeding in the bathroom by John.
Later, Natalie, having acquired Marty's session tape, confronts Marty on the roof of the Angels Square Hotel. After a brief struggle Marty ends up hanging on for dear life, saved by Natalie. Marty thanks Natalie for saving her life, but then pushes Natalie off of the roof. Natalie miraculously survives the fall and is discovered by John and Brody. When Brody goes to the roof searching for Marty, Marty knocks him out and leaves, taking Liam with her. Todd shares the news with Marty that her husband Patrick is still alive. He then takes her to the airport where he tells her that she's going to see her husband, but before Marty leaves she tells Todd that she forgot to tell John that Liam is his son. Marty gets Todd to promise that he will indeed tell John the truth, and afterwards Marty leaves town with Patrick on the plane.
