Yes

Now, given the circumstances, I've had to make other arrangements

we should go together, as friends

Why didn't I think of that?

Who are you going with?

Um, it's a surprise

You can't just take anyone

See that girl over there?

That's Romilda Vane

Apparently she's trying to smuggle you a love potion

But I am the Chosen One

Okay, sorry. Um
