However, Tripp's wife Maureen van der Bilt owns the same coat and accidentally takes Lily's, leading to her finding the letter. The next day, Maureen gives the letter to Rufus Humphrey; and he discovers that the reason William wouldn't see Serena is because he was with Lily. In The Lady Vanished, Serena meets Chuck Bass' mother, Elizabeth Fisher, and after hearing her story on why she left; realizes maybe William doesn't want to be found.

Serena and Lily return to Manhattan in Dr. Estrangeloved to find William in the penthouse with Rufus. They all sit down together and Lily explains the whole story: that last summer, she was diagnosed with cancer and has been seeing William for treatments ever since. After hearing her out, Rufus advises that she find another doctor. He then asks William to leave, which he does, but not before asking Serena to come by his hotel to talk. She goes, and they sit down together. William explains that after he went on long business trips that left Lily with no stability, she asked for a divorce. After they divorced, he became unsure on how to come back to Serena and Eric and so he just chose to stay away. During their talk, Rufus shows up at the hotel to confront William. However, he decides not to at the last minute and leaves with Serena; who tells William she needs some time to think. Later that day, William calls Lily to tell her that her latest round of test results isn't looking too good. He recommends she begin another round of treatment, and Rufus again suggests she find a new doctor. Serena argues that they shouldn't, and Lily agrees. After they all talk, William tells Serena that he thinks there is purpose in Lily asking for his help; then says he has followed her journey growing up from afar. However, after he leaves, he calls someone and informs them that their plan isn't working and he needs another prescription. He then warns them that they better cooperate because the police wouldn't be pleased to hear what they've been up to.

In It's a Dad, Dad, Dad, Dad World, William reveals to everyone that he is planning to move into the VDW's building.

Meanwhile, Eric makes it clear to William that he doesn't forgive him for not being around and that he isn't interested in pursuing a relationship with him. The next day, William finds out that he will not be approved to move into the building. Serena blames Rufus, who accepts responsibility. When Lily finds out, she leaves Rufus behind to attend a gala with Serena and William. When they're gone, Eric supports Rufus' decision to keep William out; but is surprised when his new love interest, Eliot Garfield, shows up after being invited by William. Rufus then decides to go to the gala and arrives in time to hear William make a public pass at Lily. She then realizes that Rufus was right about William's intentions. Meanwhile, Serena admits to William that she lied about her past and he forgives her.

When Serena learns that Rufus cheated on Lily, she goes to William and tells him to fight for her mother.

In Ex-Husbands and Wives, Serena tells Blair about Rufus cheating on Lily. Later that day, Holland tells everyone, Lily included, that she and Rufus slept together. Rufus adamantly denies doing so, but William offers to diffuse the situation so Lily can lie down. However, Dan Humphrey, Nate, Blair, Chuck, and Jenny don't buy Holland's story. They band together and find the whole truth: that William and Holland were working together to split up Rufus and Lily. William drug out Lily's illness by giving her medication (prescribed by Holland) that had side effects that mimicked the symptoms.

They're all about to leave when everyone shows up and shares the story. While they talk, William sneaks out of the building to get out of town. Serena follows and asks for an explanation. William says that Lily really was sick during the summer but while he was curing her, he fell in love with her again. After hearing him out, Serena tells him that while she doesn't forgive him, she also doesn't need to punish him so she lets him leave town before the police arrive.

Being a friend of the editor's, William offers to call and fix the whole thing.
