Before his demise, Isabella wrote about their progress, mentioning Jason's frequent scavenging in the ruins and his ability to find and set up the terminal in which she wrote her entries. A little over a week later, he recovered and repaired a generator, which allowed them to move the terminal and some of their equipment out to a better position for observation of the feral ghouls they were studying.
Throughout the time spent in the camp, Jason expressed continued concern regarding Isabella's increasing proximity to the feral ghouls, insisting she carried a pistol. She mentions that he has been through a lot during their time working together and acknowledges she could not have made so much progress without his assistance but wished to persist despite his objections.
Isabella continued to brush off Jason's concerns, even so far as venturing in closer to the ghouls to spend the night. He would not allow her to do this a second time alone, and built a camouflaged screen for them to sleep behind. After more progress was made in observing the feral ghouls from afar, Isabella decided to attempt to contact them directly, coating her own radiation suit in highly irradiated resin to attract them. Without telling Jason, she did the same to his suit while he was scavenging during the day. The result was both of their deaths.
