- "Happy birthday to you... Happy birthday to you... Happy birthday, dear Gladys... Happy birthday to you."
- —Family singing for Gladys.[src]
El Sereno, Los Angeles, California
Not much is known about Gladys life before the apocalypse except that she just recently turned 9 and her mother is Joanna Cruz and her father is Mr. Cruz and is neighbors with the Clark, Tran, Dawson, Thompson and Ramirez families in the suburban El Sereno community of Los Angeles.
As Travis, Nick, and Madison arrive at their house, Gladys can be seen running around on her front lawn as her parents prepare for her 9th birthday party. Later in the evening, people can be heard singing "Happy Birthday" to her and also her cries are heard by Alicia.
It is not entirely clear about what happened to her after her mother was attacked and flees back into the house, but when the military arrives, multiple body bags could be seen being carried out and also an X is spray-painted onto her home.
Since she's not present in the next episode when the National Guards are doing headcounts, it is likely that she was killed by the zombified Peter Dawson.
- Peter Dawson (Alive, Assumed)
A zombified Peter Dawson attacked Joanna Cruz on her front lawn, resulting in fresh blood splattering all over the deflated bouncy house. She flees into her home with Peter following after her into the house. On the next morning, none of the Cruzs shown up when the National Guards were declaring safety. The National Guards are seen removing multiple body bags from their house with an X spray-painted on the walls, indicating she and her family probably died.
- National Guards (Zombified, Assumed)
It is not known if the Cruzs were completely devoured by Peter Dawson. If not, then the Cruzs could have reanimated shortly, and were eventually dispatched in the morning after by incoming National Guardsmen who took over the community of El Sereno. Of course, there is still a possibility that they are shot alive by the National Guards which notices that they are infected.
