The Walking Dead: 10 Characters Who Stuck Around Too Long
8. Milton Mamet
Played by: Dallas Roberts
First appearance: Walk With Me (S3E3)
Last appearance: Welcome to the Tombs (S3E16)
The spineless right-hand man who was simply there as a weapon to orchestrate Andrea's death - something a lot of people are VERY glad about! Personally I quite liked Andrea, and felt that her death was vastly understated.
Milton served as the nerdy guy, the token virgin, and the Rick Moranis impersonator, but without the cool giant baby.
Milton could have been a great character - his backstory and ability to "experiment" on the walkers suggests that at some point he was probably a scientist. The Walking Dead didn't properly explore the Frankenstein route, but they should've done.
He did take part in Woodbury's toothless wrestling matches, but seemed disgusted by the actions of The Governor. This eventually turned him against his master, which resulted in Milton's untimely transition into a walker. The problem is that they simply kept Milton hanging around until the finale as a way to kill of Andrea. By this point Milton was just another tool in The Governor's plot.
