[Momo pokes his tongue out at bit at that, because clearly he didn't just write a letter for fun, but he makes a note that next time he does something like this he should probably just leave her a voicemail instead.]

I wasn't being that literal, but even handing them to a Turnskin would kinda suck for them, so I just wanted to make sure you knew. We don't need any more people getting burnt by certain metals than necessary!

[Momo's take is basically just minimising potential accidents - it wouldn't be a huge deal, but it's still unpleasant and he'd rather at least warn her it's a possibility.]
