Carrie “Big Boo” Black doesn’t get a dramatic death or neatly wrapped ending – she’s still alive and in prison when the series ends.

In the show’s story

  • Boo is introduced as a tough, proudly butch lesbian inmate at Litchfield, known for her crude humor, sex jokes, and deep loyalty when it suits her.
  • Over the seasons, she takes part in schemes (like Red’s greenhouse smuggling and Nicky’s sex contest), sometimes betraying people to gain favor, notably selling out Red to Vee, which gets her shunned for a time.
  • During the Season 5 riot, she gets romantically involved with Linda from MCC, only to later expose Linda as a corporate executive hiding among inmates once she discovers the truth.
  • She’s kidnapped by Piscatella and forced to watch him torture others, but she escapes physically unharmed and is among those arrested when the riot is put down.

Where Boo goes after Litchfield

  • After the riot, Boo is transferred away from Litchfield; we briefly see her in another facility (Ohio/Cleveland) rather than with the main group in Season 6, which is why she’s mostly “missing” from that season.
  • By the final season, she has landed in an Ohio-based prison where a small cluster of familiar Litchfield faces (Norma, Gina, Yoga Jones, Anita, and others) are eating together.

Her final scene in Season 7

  • In the show’s closing montage, Boo sits at a table with the other former Litchfield inmates in that Ohio prison and abruptly announces she needs to go to the bathroom, then walks off.
  • That blunt, crude line is intentionally used as her last moment on screen: she gets a simple, in-character exit rather than a tragic or sentimental send‑off.

So, “what happened to Boo”?

  • She survives the riot, is transferred to another facility, and ends the series still incarcerated, sharing a new prison with some of the old Litchfield crew.
  • The writers don’t show any release, death, or big twist for her; her fate is essentially that she keeps on being Boo in another prison, cracking jokes and living her life off to the side of the main story.
