Katie Hunt, Jessica's younger sister

The body suit you're removing from inside the Jessica suit certainly looks as if it were made from Jessica's sister Katie, but you remember that you met Katie on the way up to Jessica's room and saw Jessica at once when you went in. Either this suit wasn't the original Katie or the Katie you met wasn't! Maybe the pen-shaped gadgets can do other things besides making people into suits and stocking the wearers with suitable memories and fake personalities.

What if they can make copies of people? Maybe Katie's made a dozen of herself and all but one are now impersonating people she knows!

What now? Wearing the Katie suit and zapping yourself to get her memories might be a good idea, but Jess and Trish look so pathetic as empty skins...
