Well thought story, although I have a few questions: (SPOILER ALART)
- Why was Christina surprised that Steve is still inside the building, when it was revealed at the and that she had already been through Tempest at least once?
- I didn't quite understand how or why the tagged cockatiel didn't die after going through tempest when all the others did. I understand that it came from the future, but I don't see why it would survive the machine when the others did not.
