[ Ratchet smiles and waves back before kneeling down so as to be somewhat closer to her level. He's still much taller than her, but at least she's up to his waist now, rather than his shins? ]

It's not a problem, Korra.

[ He reaches into a compartment on his hip and pulls out several bottles and jars (?) of water. ]

I wasn't sure how much water you'd need, and how pure it had to be, so I brought a range.

[ Indeed, there's a scale -- the bottled water is sealed, while the jarred water ranges from pure distilled quality liquid, to somewhat questionable murky stuff. ]

If you could use the non-drinkable liquid first, that would help save the supply, but if pure is what you need, feel free to use it.
