Terri is found fighting off zombies in the South Plaza to protect her friend Willa Harris. When Chuck Greene arrives, she asks for help in dispatching the zombies. She then tells him that while she is able to take care of herself, Willa is not. She tells Chuck to check on Willa.
Once Willa agrees to follow Chuck back to the Safe House, Terri will also agree to being escorted.
Depending on the ending, Terri was either rescued by a helicopter sent by the Channel 6 News Station, killed by the military firebombing, or killed by the military rescue squad to cover up the truth behind the outbreak.
There is a glitch involving Terri Glass during Case 6-4: Breach. Whether or not you save her, she will still appear during this case and upon completing the case will be counted as Safe (unless she was killed during the breach). This will happen if she is Killed during An Industrial Fashion as well.
