I liked the branching paths , pretty well done.

The only thing that struck me as odd was how she got there, her agent not telling her that people who lived in that apartment have been disappearing. It just seems a little inplausible that something like that would happen because her agent should've had her best interests in mind. I think if her agent had been in on it with the complex owner because Sarah needed people to feed on, it would've explained why her agent didn't seem to have her interests in mind.

But overall, good job :)
