In my opinion, I feel like Andrea's death was fairly cheap. Why spend 10-15 minutes of an episode, most importantly the season finale, on her trying to escape her death if it was going to happen anyway. A better way for the episode to go would have been, if the Governor left Milton's corpse in the torture room with Andrea, then show nothing till the end when Rick finds her.

Another thing is why spend an entire episode focusing on Andrea escaping to the Prison if she would be caught anyway, it should have ended with her rejoining the Prison group.
