Spoiler warning: For those who haven’t finished season 4 of OITNB, plot details will be revealed ahead.
On Tuesday, OITNB star Danielle Brooks, who plays Tasha “Taystee” Jefferson on the series, took to Twitter to share an adorable – but heartbreakingly sad – photo of herself with costar Samira Wiley (a.k.a. Poussey Washington).
“Our last moment together from season 4!” wrote Brooks, 26. “Love this one to the moon and back! @oitnb #poussey #taystee #taysteetuesday.”
Wiley’s character Poussey made her sob-inducing exit in the final scene of season 4’s penultimate episode, dying during a prison-wide protest after being pinned down and accidentally suffocated by an untrained prison guard.
Of saying goodbye to her on- and off-screen best friend Brooks, 29-year-old Wiley recently told PEOPLE the two “both [lost it].”
“Especially at the time when she had to come over and discover me – we had to do that scene over and over again for camera,” Wiley said of Brooks, whose character sprints over to Poussey and discovers her body lying lifeless on the cafeteria floor.
“There was a time in between scenes that we went back to my dressing room and just broke down,” Wiley said of the emotional scene. “I just broke down crying in front of Danielle. It was hard. It was going through waves of me trying to take care of everybody and then it hitting me all at once and then it hitting Danielle all at once. There was laughter and tears all throughout that day.”
Season 4 of Orange Is the New Black is currently streaming on Netflix.
