She ends up breaking into Ryan Matthews' house, claiming that he destroyed her relationship with Dixon, and threatening him with a bottle of wine unless he fixes everything.

Dixon remembers his birth mother, who had bipolar disorder, displayed the same symptoms, and realizes that Silver suffers from it also.

Soon, Silver finds it unbearable to go back to West Beverly High due to the gossip surrounding her recent behavior, and decides to move to St. Claire's School.

She initially tries to make a fresh start, but another girl recognizes her and wants her to be honest with the other students, going so far as doing a hunger strike until Silver sends the video to everyone.

Silver begins to feel the growing pressure of her studies, private life, and taking care of her mother.

Just as Silver and her mother are finally catching up with each other, Jackie suffers a cardiac arrest and ends up being confined to the hospital.

[6] Due to her work in the Blaze, Silver develops a close bond with Navid Shirazi and helps him with his problems regarding his father.

As she gets to know Navid, she realizes what a great guy he is and slowly starts to develop more romantic feelings for him, this is particularly encouraged by his recent relationship problems with Adrianna.

In 'The Best L'eid Plans', it becomes apparent that Silver's feelings for Navid have grown stronger, when they spend the night in her room talking about his father.

When Adrianna pretends to think it was one of Navid's ex-girlfriends, she tells Silver she is going to send a nude picture of her to the entire school.

She then begins to behave strangely: she dyes her hair in red, she calls Christopher several times, the man who she had an interview with for NYU in the afternoon, etc.

After receiving some distressing news about NYU, Silver has an emotional breakdown, causing Navid and Dixon to stage an intervention to make her go to a mental hospital.

Fortunately, Silver finally discovers the truth during Ivy's bachelorette party when her medication falls out of Adrianna's purse.

Silver has the opportunity to create campaign videos for political candidate Marissa Harris-Young, who is running for public office against Teddy's uncle Charles.

In "Babes In Toyland", Silver gets accepted into New York University and hopes she will be close to Navid in nearby Princeton, but she later has second thoughts.

In Blood Is Thicker Than Mud, Silver, working as a production assistant on the set of Liam's latest movie, confides in him about her fears of having an inherited cancer gene.

In Blue Ivy, Silver and Liam have sex after she knows her test results are positive for the cancer gene.

In Bride and Prejudice, Silver wakes up in Liam's bed from when she ran into his arms after her breast cancer gene diagnosis.

In the season finale, Forever Hold Your Peace, Silver has vehemently decided that she wants to get pregnant sooner rather than later to ensure that she can have a child before preventative cancer treatments.

Teddy then brings in Shane's sister, Michaela (Lyndon Smith) from Washington, D. C. She agrees to become Silver's surrogate.

As they do, Annie and Naomi's half-brother Mark (Charlie Weber) arrives in LA and Silver and Ade make a pact to not let a guy come in between them.

Because she's so devastated, Michaela decides to go back to Washington and asks Dixon to let Adrianna take her place at a Spencer Blaine Tribute concert, to which Ade agrees.

When Silver arrives on the scene, she begins to regret calling Ade a "hateful bitch", fearing that could've been the last thing she ever said to her.

She displayed some classic bipolar symptoms, including erratic, reckless behavior, racing speech, grandiose ideas, hypersexuality, lack of sleep, euphoria and confusion.

In Season 2, her hair was cut short and her sense of fashion has become more girly due to Naomi and Adrianna's influence but still remains her original style.
