[previously unknown secondary uses for windsock hoodies: impromptu scarves, which John has wrapped around most of his face, because what even is this. Admittedly it doesn't help the arm situation much, but that's what he's trying to find a jumper for.]

Okay, it wasn't this cold last time! It can't have been that long. [with a glance at the ceiling] Seriously, what is this place's deal?

But you don't?

What was the puzzle Professor Layton made out of it?

It was one about figuring out what we were eating based on the cost and a couple of other clues. I can't remember the whole specific thing.

Oh… well, that's okay. What about one you do remember all of, then?

[YOU WANT TO DO PUZZLES? Luke grins.]

Sure! You have eight coins and a scale. One of the coins weighs just slightly less than the other seven. Using the scale, what is the fewest number of times you would have to weigh the coins in order to find the odd one out?

[well… why not? John hums, crossing his arms and thinking about it.]

If there's a difference, then you'd notice it each time. So if you divide them equally… four to each side, then take off the four that are heavier, put two on each side, and then one, that makes three times.

That's not bad!

But I can do it in fewer.

What, really? How? Do you skip the first measurement, or what?

What? No, you've got to make a first measurement. It just doesn't happen the way you expect.

It doesn't? [He frowns, thinking this over.] Okay, so… that means it's a different number. Right? So… do you leave four out, and put two in on either side of the scale first?
