Brook Soso is an inmate at Litchfield Penitentiary, portrayed by Kimiko Glenn. She is first seen in "Hugs Can Be Deceiving" as a brand new inmate, being shown around and introduced by Lorna Morello on her intake day.
Soso is principled, passionate, and kind, but she is very talkative, which irritates many of the inmates. Generally, her principled protests are undermined by fellow inmates who don't want to make waves and risk trouble. Later, Soso becomes disgusted at the prison conditions and protests by staging a hunger strike, which none of the other inmates take seriously at first. Sister Ingalls, Taylor and Jones eventually join her in the protest. They write up a list of demands for Piper's prison newsletter, but the protest eventually fizzles out under pressure from the warden's office.
Soso is half-Japanese, half-Scottish, but she is taken in by the white women as soon as she arrives at Litchfield. Her Asian features make her the target of fetishisation at the hands of Big Boo, as well as being assumed to be submissive and compliant by Boo and Piper.
After she arrives she refuses to shower, citing that people should live with their natural odors, and does nothing even after Pennsatucky bluntly tells her that she smells. When one of the prison officers, Wanda Bell, tries to haul her into a shower room, she drops to the floor as a display of "passive resistance." However, Bell is victorious in their standoff and forces her to take a shower, which she does while crying.
For a list of episodes featuring Soso's flashbacks, see here.
Soso is of Scottish and Japanese heritage. She grew up in a strict household with a mother that pressured her to be the best at everything, including piano ("Trust No Bitch").
[...] ("Don't Say Anything")
According to Sister Ingalls, she is a "dirty hippie who has no idea what peaceful protest really means." Progressive but naive Soso claims her parents named her after "Brooke Shields, except without the e", but also said her parents later told her she was named after a "babbling brook." Soso was arrested for protesting logging by living in a tree so it couldn't be cut down. She volunteered at an organic farm in Xenia, Ohio, with her best friend Meadow ("Hugs Can Be Deceiving").
On Soso's first day at Litchfield, she becomes acquainted with Piper, who she believes is very much like Meadow ("Hugs Can Be Deceiving"). After Piper tries to trick her into becoming Big Boo's prison wife so she can regain a lost blanket that Boo doesn't want to give back, Soso gets very offended, calls Piper "sick", and runs off crying. Nicky finds her and offers a listening ear, which results in the two having sex in the chapel; it's revealed that it's not her first time having sex with a woman.
Soso becomes very depressed because she wasn't making friends with the other inmates due to her constant talking, why she's regularly frequenting Berdie Rogers who's listening to her problems. Her counselor Healy instead has her go to the medical facility so she could take anti-depressants.
She ends up using diphenhydramine (Benadryl) to attempt suicide through overdose, but Poussey discovers her passed out in the library. Poussey, Taystee, and Suzanne save her by making her throw up the pills in the bathroom. The group then helps her get back on her feet and continuously wakes her up to avoid a trip to the psych ward. Soso then becomes friends with their crew, and she is seen holding hands with Poussey, implying a budding relationship ("Trust No Bitch").
A romantic relationship between Poussey and Soso develops. After CO Bayley improperly restrains Poussey and causing her to accidentally suffocate, Soso is devastated. Norma comforts a crying Soso by rocking her and singing, and Soso is later seen getting drunk off of the buried hooch that Poussey was making.
- Nicky Nichols (one-night-stand) - In Season Two, Nicky and Big Boo have a competition to see who can have the most sex with other inmates; Boo sets her eyes on Soso but Nicky ends up having sex with her in the chapel. Nicky and Brook have sex together. In Season Three, Nicky goes to hide her stolen heroin in the laundry light-fixture. Brook is working there and asks whether her and Nicky can at least be civil even if they're never going to be girlfriend-girlfriend, but Nicky, panicked that Soso nearly spotted the heroin, coldly asks how that was ever supposed to work as Soso never stops talking. An insulted Soso remarks that now she knows that using people and throwing them away is Nicky's "thing" ("Empathy Is a Boner Killer").
- Poussey Washington (girlfriend) - Initially civil, the two were on rocky ground after Brook offended Norma's group. But Poussey later found Brook unconscious in the library after she took an overdose of Benadryl. Poussey was desperate to help Brook, even to the extent to induce vomiting with her own fingers . When the inmates escape Litchfield, Brook is seen floating alone in the river. Poussey swims up to her and holds her hand ("Trust No Bitch"). (For more information see Poussey and Soso)
