Iain was with Rui in the Medic Lab, and he checked her to see how she could identify Shadow Pokemon...
"Do you have a Doctorate degree?" she asked after a while, and Iain answered, "Let's just say… I am good in Biology…"
"Then why are you a Trainer instead of a Professor or a doctor?"
"Would you change your job if you have so much fun in your cuurent job?"
"I can see your point but… so far, I know Trainers are not that well paid… they live only from the fights and most of the fights doesn't bring the amount you need to live off of…"
"David and I are very good trainers… and we have a few places where we can make money… For example, we know a beach where, from time to time, pearls and other items appear…"
"So that's you make your money…" she mused.
"Indeed. And David makes a part of his money with small inventions we made as well…"
"Wow…"
"Yeah…" said Iain, and continued his work.
After awhile, he came to a conclusion: "It seems by a usually undetectable defect in your eyes, makes you able to 'see' the dark aura of these Shadow Pokémon… if we could find out what causes this Aura particularly, and how this error in your eyes makes them visible, we could make scopes which would allow us to see this Aura as well…"
Rui looked at Iain in an understanding way, but Iain noticed something on her back.
"What is that?" he asked and took it from her clothes "I don't know…" was her reply as CyMe came in. "Hey! This looks like one of the senders David makes from time to time!"
"Senders?"
"Yeah… to identify the position of objects… very effective, and David told me that they are able to be detected in underground as well… he makes some from time to time and sells them…"
Iain became nervous, and splashed some water on it. As the device sparkled, Iain cursed and rushed to the workshop of his friend.
"David! We have trouble!"
"Why?"
"Rui had one of your senders, and it was active! Whoever put it on her, he now knows where we are!"
And just as Iain ended his sentence, the alarm went off, and David sighed, "Next time you come with bad news, please prepare the defenses first…" and rushed off with his Pokéballs.
Iain went back to Medical Lab, and saw Rui and CyMe still there.
"Come on! We need to get into a safe place!"
"I don't think so…" said a voice, and as he turned around, he spotted three trainers in front of him, in weird soldier-like clothes…
Iain cursed under his breath; this will be difficult!
