Betrayal
silver!Yogi considers Circus to have betrayed him.
He had high expectations for and once trusted the organisation that rescued him away from the abdominable laboratory and to take care of both Yogi and himself.
But Circus broke this trust as they kept treating him as if he was one of the Valga, always sedating him whenever he took over. This was despite how he protected Yogi from death and fought the Valga whenever things got desperate.
At this point of time, he still continues to serve Circus because of Yogi and his own hatred of Kafka.
Despite all these, he holds Circus in high regard because Circus was his home and he owes them a lot. This is why he still wants to be accepted by Circus although he knows that it’s near impossible for someone like him to do so.
