Take a boat, I have my wand to conjure fire.
Build a bridge, it shouldn't be too hard.
Walk around, I'm not taking any chances.
Seek a safe way across, no matter how long it takes.
A jeweled dagger
Tightly bound scroll
Book of all the past students of Hogwarts stretching back to the Founders time
A cure for Dragon Pox that is almost complete
A stash of weapons
The Sorting Hat
Turn them into a toad
Cast a Full-Body Bind Charm
Use Devil's Snare weed to entangle them
Throw a vial of Shrinking Potion onto them
To be fair to everyone.
What's best for you personally.
Making the smartest and most sensible choice.
What is most noble, even if you might lose out yourself.
