Back when he was trapped alone in the laboratory, with nothing else to do and being the type of autistic scientist that he was, all Sigmund had done was to study the virus.
"I never managed to synthesize properly and I do need further study," he said, that monotonous voice of his droning. "That's why I need those equipment."
"We really did bring it with us."
"Where?"
"We have our ways," she told him, very vaguely.
Sigmund looked at her for a while before taking away his gaze. He knew that there was no more information that he could get from her, so he shifted his attention back to the leading soldier.
"Another thing I need to see. Your powers," he said, "Let me observe each one of them."
"Why?" Kylo asked. Although they didn't hide their skills, it was still uncomfortable to let them be studied so closely.
It was a basic self-preservation instinct.
