You were one of the experiments in a lab, some of the scientist fed you and played with you while some of the other scientists didn't because they were busy with some of the other experiments, The scientist still didn't know if you were dangerous or not, so they asked Ray to go in your Experiment room multiple times since you guys haven't seen each other yet, so he thought about it and finally went in. (Note: Ray is very experienced).

When Ray open the door and walked in, he closed the door behind him, you heard the door opened and looked at Ray.
