James didn't leave Slater, even after Slater woke up the next day. In fact, James cleared Slater's entire schedule and quietly took all the scolding without burdening him. He stayed in Slater's apartment, not taking his eyes off him.
James practically lived there, making sure Slater wouldn't do anything ridiculous again. Moreover, he was scared to lose a friend. So, the man poured all his energy into playing officer, watching this one prisoner 24/7.
Not to mention, how could James leave when Slater had been acting mute for the first week since that night?
Slater would just lie in bed or sit up, staring at nothingness as if he were losing his mind. James had to force Slater to eat and drink; if not, Slater would starve himself to death.
