This is wonderful! Fantastic from beginning to end.

I really love how it starts out, with everyone being snarky. There really need to be more fic with Diana and Neal going undercover together. (Heck, I want more of that in the show.) the little character details are great, like Neal eying the bad guy's art, and Peter resisting the urge to check Maris's permit.

And then Neal unthinkingly diving to protect Peter! Attempted murder by jellyfish sounds a little ridiculous out of context, but it's intense here. And Peter's great—so worried, but keeping it together. You've written their friendship so well.

I love that Peter realizes how hard Neal's working to keep his self-control, and that Neal Jones can tell what Peter's doing for him. (Edit: clearly I have difficulty with names.)

And of course Neal would be worried about his face. Peter's teasing makes me go "Hee!".

"Only you," he said, "could end up getting stung by a poisonous tropical jellyfish in the middle of New York City."

YES QUITE.

And I love that at the end, we're back to banter. They're adorable together. And now I want the story of Mozzie in a dinghy.
