[Leaping before he looks is one of Nora's primary traits -- it's just usually not so... literal. Well, at least he was actually swan-diving into water and not off a mountain cliff or into a black hole. He might hesitate a little more before those. Very maybe.

Recklessness is also another middle name (he has a lot of middle names that usually rhyme with -lessness), so this is not the last you're seeing of it, even without the Charm point. He did have Regrets once he was actually down in the water, because getting buffeted around in salt water (ick) and smacked against the ship's hull was a real thing, but swimming is a little particular to him. In terms of being a Metaphor, I guess, but also in terms of I can't lose to this ramped up to 11 with a side of fuck that damn Aqua Division General I'll show him.

Actually, considering the ears, it might be a little less of a Metaphor.

Here and now, he still hasn't picked himself up off the floor or looked up, but he does vaguely try to splash Tieria with the considerable puddle he's dragged up with him. It works about as well as you'd expect.]

You... underestimating me! I'm going to make you... regret this... I'm going to...

[Splash, splash, drip.]
