If looks could kill, that man would certainly be dead. Maybe not by Korrin, but the agitated bear could easily finish the job. If their situation wasn't so urgent, she'd stop to lecture him. As it is, if he doesn't move fast enough, she'll ungraciously shove him out of the way. He can complain to the Inquisition later.

"That's the river ahead! We're almost there--" And that bear is getting just a little too closer for comfort, so Korrin renews that Barrier spell. If Rey's close enough, she'll get protected again, too. Otherwise, Korrin will just have to hope that the bear doesn't lose interest in her glowing, waving blade.
