That or she’s just hanging out in the ruins of Raccoon City. Plenty of normal people have survived buildings collapsing into them and she managed to come back after three days without vital signs.
The entire Lisa/Jessica/George plot line gave such a mature perspective into the extreme heinousness of Umbrella and what they’re capable of. What they did to that family. Cruel, unusual, and downright medieval, still doesn’t underscore how psychotic and horrifying those researchers must have been. Truly chilling.
I was terrified of Lisa when I first encountered her but after learning about her past and hearing this along with her saying mother all I could say was "I'm so sorry" while crying.
