"In a sec." It wasn't that easy to get a bridle on a mouthy horse while handling a chatty dog's leash at the same time, and so Sif was doing a little bit of a balancing act -- but once that arbitrary 'sec' was over Katie was bridled, the crossties were hooked to her bridle and not the halter she was no longer wearing (it was now over Sif's shoulder) and she was still holding Jotnar's leash.
Once she had a hand free, she gently ran her fingertips underneath Katie's girth, and nodded. "Yeah, you're good. We'll spot the stirrups in the ring. Going to lead her?"
This was, based on Sif's expression, obviously a challenge -- but a light one.
