Kora inclines her head - the brief spat passes, and she doesn't see the reason to dwell on it. There are, as noted, pressing engagements occurring - you know, like the zombies.
"Which traps us," Kora notes, mildly, "but they seem to move quickly after the first shot - they feed off the kinetic energy from the spells, I'd wager, it makes them faster. Stairs will be harder for them to grasp in the first state, so--hurry, please."
She somehow gives the impression of being able to jog and being totally chill with this situation! It isn't stressful! At all! (Kora, fff.)
