... I HOPE it'll dry.

[That's really all he can do. He didn't think he was in the water for long enough for permanent damage, but this is also one of his first jaunts into pouring water without Alphys on standby. It wasn't on purpose. He readies himself to move and fortunately, his body doesn't do anything too weird except for a sharp twitch of his ankle.]

But that's a brilliant plan. Oooh, actually! I noticed something while I was getting out of those rooms. I saw an outlet! [Mettaton smiles down at Keith, recovering a little from his distaste for his situation.] Surely there must be others in this... place. Do you think you could help me find one? I should wait until I dry out completely, sure... But after spending all that time at Astoria's temple with no way to charge my battery, I'm in desperate need of a charge. What do you say, Keith-darling?

[Conveniently omitting the detail that the current body he's using drains his battery faster. Totally unimportant. Possible water damage compelled him to check its function, that's all!]
