|Lilly Caul Gallery|
Little is known about Lilly's life before the outbreak. She worked for the U.S. Air Force at the Robins Air Base in Georgia. Her father, Everett Ray Caul cared deeply for her, and sacrificed himself to protect Lilly.
Lilly went to high school, with Megan Lafferty, where she wanted to be something with fashion. She and Megan shared nearly everything.
Georgia Field Camp
Lilly and Megan Lafferty decided to stick together. After a while they met up with three families, one of them being Chad Bingham's. As time went by they got more and more people to join the group, untill there was nearly one hundred survivors, including Josh Lee Hamilton and Scott Moon. Josh and Lilly got caught in a relationship. As the Georgia Field Camp was attacked by zombies, Lilly escaped, leaving Josh to die. Some of the survivors managed to save Josh, seconds before being devoured. Lilly felt ashamed by leaving Josh, even though he tried to forgive her.
Woodbury and the Prison
Lilly is seen first in Issue 46 within a Woodbury crowd, having a surprised reaction either at seeing Michonne coming up behind The Governor, or because of the false news said by The Governor about Ricks' group killing Tyreese.
It was Lilly who shot and killed both Lori and Judith Grimes. After shooting them, she blamed The Governor for Judith's death and became extremely distraught. As a result she killed The Governor and kicked him toward a wall of zombies. The Prison then became overrun with zombies, causing the Woodbury survivors to run inside for safety.
The comic does not show her death, but it's revealed that she and the others had run out of ammo. It is currently unknown what becomes of Lilly or any of the other Woodbury residents.
Creator Robert Kirkman wrote: "I'm not going to say (the Woodbury survivors) were all killed (when their bullets ran out), but it's very unlikely that we'll ever see them again. The prison is dead to me. I've moved on and so have the characters."
This list shows the victims Lilly has killed:
- Brian Blake
- Lori Grimes
- Judith Grimes (Caused)
- Numerous counts of zombies and possibly unnamed people.
The Walking Dead Novel Series
- Lilly was the only female attacker from Woodbury specifically named.
- In The Walking Dead Survivors' Guide, Lilly is listed as presumed living.
- Glenn and Lilly met in the Walking Dead Video Game. The two of them would have had an opportunity to cross paths again if Glenn hadn't left with Dale and Andrea on their trip back to the farm.
