Jacob was taking a typical run around the Academy grounds when he heard the gates open. He always turned his head to look when this stuff happened, but when he saw a barely familiar face that hadn't been around, he tripped, losing his prosthetic in the process. Cursing as he forced himself up with only half his leg, he watched the new arrival in shock. He'd barely known the girl, hell, he barely knew anybody in the Warehouse crew. 

Still, he kept up to date with most of what had been happening, especially now that the training with Balthazar was a thing. Many of them were worried, and he was too. Though, his worry was more about the long-term implications of what this group of people were doing. Fumbling to grab the lower part of his leg, Jacob carefully reattached it, standing up to make sure everything worked before running over to her, calling out to a few people on a bench. "Quick, let's get her to the infirmary!" Anything else could wait. The questions could wait. The worrying could wait. Right now, they had to do something, and he was pretty sure of the proper course of action.
