Jude had already gone into his own world of thought after turning away from the elevator, but was halted by the hesitant call from behind. He turned slightly to face the man he'd been in the elevator with, and then more fully as he was approached. At first, he blinked in surprise at the words slightly babbled at him at him, but then a grin came across his features easily just as he was handed the sweater. It was warm against his already chilling arm as he said, "That's very considerate of you. Are you this kind to every ignorant stranger you meet?" It was said in a joking fashion, of course, but he acknowledge the gesture mentally. Most of his subordinates seemed to fear talking to him about anything not relating to work when they first met, and since his life had been centered in the hospital lately, he'd grown used to the isolation his status brought upon him. Of course he'd worn down the long-term staff, but the new ones always were the same. The non-surgical staff were even worse. He supposed the limited interaction between the different departments would make communication seem normal, but had never really thought about it before. However, he wasn't sure if it was entirely normal to offer your sweater to someone you just met, especially when it was drastically cooler than an agreeable temperature to go without such protection. Not that he thought any worse of the man, in fact, the opposite seemed to happen - he had a rather good impression of this quirky person before him so far.
