A young woman living at the Severn City Airport, by the name of Lily Patterson, is suffering from severe Effexor withdrawal symptoms. Effexor is an anti-depressant, which also acts to reduce stress. If Lily didn't need her meds before, she's certainly going to need them now, as she faces up to the imminent collapse of civilization.
Unfortunately, despite everyone's best efforts, a fresh dose of the medication she so desperately needs cannot be found. Food is still available, though; Tyrone pops out to go hunting and returns with a deer. But in the meantime, Lily's slipped away, and no one knows where she is. A search party is put together to go find her but all to no avail. Lily's lost, seemingly forever. Surviving all alone out there in the wilderness would've been hard enough, but without her medication, it's almost certain that she'll die.
