They didn't have much time, before the few creatures left made their presence known, but now that most of the danger had passed there was a better chance they'd make it back to safety without something horrendous happening again. Killian handed Jefferson his baby sword, because he assumed that his friend would want to be the one to walk back with Emma and comfort her, and he'd need something just in case. Swan's magic, if it was like most types, could be unpredictable when she was under emotional duress.
He stooped to carefully lift Snow's body, carrying her bridal style for the time being. Unsure about how long the body would remain (because the two times he had died, he hadn't thought to ask about that particular aspect later), well, with them, he supposed if it was important to Emma they really ought to try anyway.
Besides, he couldn't resist her teary face. Bloody hell.
