Doc. Leon has put Ken to sleep successfully, he has taken Ken's fingerprints and blood samples in the second lab; the second house.
Doc. Leon says to himself if Zen finds this out, he going to beat him up or even kill him but this is for Zen's future.
Doc. Leon says, "Ken you are a sleeping beauty now, while you are sleeping you can remember Zen. I don't have any medication for memories for now."
Doc. Leon puts up everything he can for Ken so that while Ken is sleeping in the lab no one will disturb him.
Doc. Leon puts a monitor tube on Ken's body and links it to his laptop so he can monitor Ken's condition. He can see Ken, wherever he is without coming to the lab. (This laptop Zen and Joe didn't know about nor the "TT Hospital"; it's a brand new laptop Doc. Leon bought it a few months ago, he was thinking of using it for personal studies but since there is this emergency of using this laptop he uses it.)
