Wow! Nice update my friend. I was away in a trip and I received your update message in my mail and you don't know how much I want to check it out. I finally came home to see it and I got surprised to see a second one.
First of, Rachel and Rob evening was nice. She certainly still have problems with her size, but Rob knows how to cheer her up indeed. About Sydney, she has a kind of sick crush on on Rob. She wouldn't teasing him that way is she didn't want something with him.
Now, about the device, since Pym warmed her that there may be some side effects, it will be interesting if there could be some. Sydney was kind of dumb for not trying the device in other woman first. So far, the device can transfer her size to Rachel leaving her as a midget and Pym can ask at the mini-gts Rachel to finish her off.
Also, let's hope the recently developed cousin can make an heroic entrance to save her aunt.
Nice effect with the transfer ray my friend.
