"Huh? Oh! Right! Well, the fire escape's not very big, and there are ponies from upstairs using it as well. It also turns out a lot of ponies suck at using ladders. I was thinking, if we had a few mage ponies, we could use their shields to make a big slide and get every pony out of here a lot faster. We're only four storeys up here, so it'll be fine. It could even be fun!"
