If that alarm is anything as shrill and deafening as a fire alarm I feel for them. Those are the worst. I was wondering what the alarm was for and I guess the team found out the hard way. It's a good thing that the Hub doesn't have any open windows for anyone to float out of. For a moment there I was worried about Ianto getting crushed to death. Very interesting idea for a story. I liked it!
Author's Response: Thank you! Think fire alarm times about twenty and you'll be close to how awful it was. I wouldn't have really crushed Ianto, but he certainly felt he was getting flattened. I have no idea where the idea for varying pockets of gravity came from, but it was fun to play with.
