Haley, portrayed by Alexa Nikolas, is a character in the television series The Walking Dead.
Gargulio is one of The Governor's enforcers tasked with protecting Woodbury's wall. She teaches Andrea how to use a bow and arrows, and tells Andrea she had to kill her father and brother when they turned.
She gets angry when Andrea crosses the wall (breaking The Governor's rules) and at Andrea's delight in killing a "biter". Maggie Greene shoots and kills Haley when Maggie Greene and Rick Grimes storm Woodbury to save the Dixon brothers.
