Viktor was never repulsed by your condition. He understood how you gained your condition. Like his conditions, they were gained by the harsh conditions of the understands. While he uses a cane and a back brace, your problems were mental. You were schizophrenic which made you see things and talk to people who weren't real. He didn't mind, but he knew that it took a toll on the both of you.
You usually took pills to keep the hallucinations to a minimum but after the pharmacy banning you because of your Zaun origins, which meant you basically went insane. Viktor tried everything to get the hallucinations to calm down but they were ruthless.
One day, Viktor limped in from a day at the lab, when he saw you lying in bed, mumbling and looking at the ceiling. You were having a full conversation with someone he couldn't see. It broke his heart.
Viktor: " Who are you talking to dear?"
