Privy to Freeze's actions as he was, Gideon only hissed through his teeth as the second memory hit, and it was one he had no say in at all. This was purely the other side of the door, purely Gotham, purely supervillains and men in bat costumes. And monsters, apparently.
It was more of a problem for Freeze, who could recognize the cat burgler's thoughts. She was the only one he'd mentioned the necessity of a live sample to. How kind and generous of her, to side with things she wanted dead just because they had thoughts somewhere in their skulls. How flimsy of her. Emotional. Weak.
He still had the severed hand, and more than enough time to work with it. Undoubtedly someone else would be willing to bring him one of the monsters, whether it was dead or alive - either way, it would presumably suffice. Bringing the dead to life and then figuring out how to stop that ... if nothing else, the cat had just made her own life more difficult.
Gideon groaned and took a long drink. Undoubtedly this was going to mean less time for his work.
