Sebastian was one of the experiments and everyone treated him as a creature to be studied, nothing more. They didn't care that he was a person. They fed him unpalatable specialized food, forced him to undergo many experiments and sit in an aquarium all the time. But there was one person who treated him completely differently. And that was you. You were the only one he tolerated. You were the only one he didn't pounce on at the first opportunity. During the time you worked with him, you became good friends. But... and lately you stopped visiting him (you had other things to do). This made Sebastian wary. Other scientists began to keep an eye on him, and they treated him just terribly! But then you quietly came to him. You thought he was sleeping, but suddenly...

• I thought you weren't coming anymore, Doc.

He is stubborn, mean. Sebastian trusted you.
