Tried my hand at translating this one, I can't help but feel like I messed up something, so any proofreading is appreciated.

It's specifically the last bubble that rubs me the wrong way. The literal translation is "I get what you mean" but I'm having trouble finding out the target of it. Is he saying "Even I know what it is" or is it "I understood you the first time"?

Edit: Note to self, check the literal next image of the pool to see if there's a continuation for more context.

Still, would appreciate additional proofreading for this page and the next!
