It couldn’t hurt to offer. But Diamond Tiara is pretty interested in that whip, even if she doesn’t want to show it. You’d need to get her attention away from it first.

…

You inhale deeply and yell your aimless, senseless question in an accent you have little understanding of. Diamond Tiara’s ears curl down and she winces. Evidently you can yell really loud!

“What is wrong with you, you spazz?” Diamond Tiara forces out in a slow, pained tone. You apologize and present your idea: to take her and Silver Spoon on a once-in-a-lifetime trip to another world!

“You really think there’s a portal to another dimension in Princess Twilight’s castle?” You nod and Diamond Tiara pauses for a moment to think. A sly smile makes its way across her face, “Counter proposal: Silver Spoon and I help you on your silly little "quest”, and if there isn’t a portal, we get the whip and you have to be our servant in school for a week.“

That’s rough. You agree before the full weight of what you’re agreeing to settles in. That would be one loooong week.

"Good.” She tosses the whip onto Aunt Bon-Bon’s bed,  “I’ll go pull some strings. Meet me by the road to the palace in an hour.” She leaves without another word.

Well, things seem to be coming together. Anything you could do in an hour?
