It's the middle of the night, and we're hearing double entendres. We're not sure what they're talking about, but it's clear that they mean the same thing: "Hey, I'm the guy who sent you a challenge letter . . and I almost injured a human . there's nothing to be done about it" . So, what's going on here? Well, it turns out that the challenge letter was sent by a boy named Nemo, who's clearly not a very nice guy. Nemo's got a message for us: "Don't worry, we'll get back to you later" , which means that he's not going to tell us anything about what happened in the previous scene. We don't know what Nemo wants in return, but we do know that he wants to get back at us.
