Milton Mamet is a fictional character from the American television series The Walking Dead and was portrayed by Dallas Roberts.

In the episode "Say the Word", Milton helps to wrangle captive walkers and one tries to bite him, but he is protected by duct tape that he wrapped around the sleeves of his jacket.

In the episode "When the Dead Come Knocking", Milton tests, with Andrea assisting, the possibility of communication with the residual human consciousness believed to still exist in the undead.

To this end, he repeatedly asks emotionally significant questions to Mr. Michael Coleman Sr., a voluntary test-subject dying of prostate cancer, in the hopes that after Coleman dies and reanimates, he may, despite his zombified state, initiate behavior that implies he understands and perhaps retains emotional reaction to the questions asked before death.

In the episode "The Suicide King", he talks with Andrea to find out how many people were injured in the attack by the prison group, and later tries to calm the upset residents.

Rick's group, aided by Tyreese and Sasha, discovers the torture room, Milton's body, and a dying Andrea who soon after kills herself to prevent reanimation.

[5] In his review of "Say the Word", Handlen refers to the scene of Merle and Milton killing zombies as "a kind of alpha-male game".

Milton spends weeks working with a man with prostate cancer, trying to instill a sort of sense memory around a series of questions in order to determine if anything of his mind remains after death.

enjoyed the interaction between Milton and Hershel in "Arrow on the Doorpost", calling it "a cool scene to see two 'normal' people having a chat while two other guys are face-stabbing and head-smashing zombies".

That's the straw that breaks Andrea's back, and it's also, apparently, enough to make Milton work against the Governor in his own way; in this case, that means burning the pit and van zombies Martinez had set aside from the prison assault.

[12][13] The on air portrayals of Milton and Andrea's deaths and the characters who discovered their bodies differ significantly from what was originally taped.

[15] Erik Kain of Forbes.com noted in his review of "Welcome to the Tombs" that "Many moments in the episode were great", especially the opening scene involving the Governor and Milton.
