"Internment" is the fifth episode of the fourth season of the post-apocalyptic horror television series The Walking Dead, which aired on AMC on November 10, 2013.

Hershel starts closing everyone's cell doors, following the advice of the dying Dr. Subramanian, and kills those who succumb to the virus away from the others' view.

Rick returns to the prison and informs Maggie, who had been clearing a large herd of walkers at the fence, about banishing Carol for killing two of their own.

Maggie heads to the visitation room, kills the remaining undead and shoots the intubated walker, allowing Hershel to retrieve the bag for Glenn.

Right after they finish, the van with Daryl, Michonne, Tyreese, and Bob arrives with the medicine needed for the remaining sick, and Carl reassures his father that they will be all right.

Critics praised the action, resolution of the illness, Scott Wilson's performance as Hershel and the ending scene with The Governor's return.

"[3] Roth Cornet of IGN gave it a very positive review, scoring it 9 out of 10, stating that it "was filled with some great walker and machine gun action, but ultimately served as a moment to demonstrate the importance of a balanced approach to both leadership and parenting.
