At the precinct, Hank and Wu are boxing their belongings and fussing with their resignation letters.
(I appreciate that Hank used company resources to print his.)
Skyscraper Renard and pocket-sized Wu engage in the most mismatched staring contest in history.

Have you noticed that all of Nick and Adalinds phone calls these days start with, Are you okay?
All things considered, their relationships doing pretty well amid the weirdness.
Bless Monroe; he immediately starts worrying about his pregnant wife handling the spell ingredients.

Oh, and also, remember that time they did this spell and Juliette turned into a Hexenbiest?
On the blackmail front, Renards all about multitasking.
He needs to appoint a loyal successor to be police chief, and he needs Jeremiah to go away.
Unfortunately, a bloody shirt calls for a wardrobe change.
Gotta say, Adalinds awfully calm about Nick going through with this.
When Renard enters the house, Adalind shoos Monroe into the closet and asks, Whyyyy are you home?
in a hilarious Nothing to see here!
Renards rightfully suspicious about her niceness, but she lies that shes just getting with the program.
Claire Coffees freaked-out facial expressions in this scene absolutely kill me.
NEXT: Blood on Renards shirt?
You should probably take them off.
And then there stands a shirtless, woged Renard!
I didnt know it was possible to do a David Giuntoli impression, but apparently, tis.
Then the group coaches Renick through Being Sean Renard 101.
Renick says it feels weird being this tall, and Monroe suggests he move a little more … Renard-y.
More full of yourself, Rosalee suggests.
So Renick puffs out his chest and tilts up his chin, getting into character as Hank walks in.
When Renick tries to apologize, Hank shrinks away.
Guys, this whole scene is amazing.
Not only is this my favorite Sasha Roiz episode ever, its the funniest Claire Coffee has ever been.
Did she kill somebody else?
asks her distracted father.
Realnard, in a red tie, reluctantly agrees to stay and talk about Dianas unique educational needs.
Oh, and incidentally, Nick Burkhardt did an outstanding job during his recent undercover stint, Renick says.
The best part of this sequence?
Just … A+, everyone.
Renick fumbles his way through the conversation.
Luckily, he knew that Renard came home with blood on his shirt.
He tells Grossante that his sloppy crime scene habits are a deal-breaker.
Man, Sasha Roiz even walks differently as Nick-as-Renard.
The reporters clearly think hes losing it.
Werent you just wearing a different tie, sir?
one of them asks.
This confirms everyones fears that the spell might work differently on a Grimm.
Done messing around, Realnard calls Hank and barks, Put him on the phone.
They both toss their guns, and Renick sucker punches Realnard as hes taking off his coat.
ITS A ROOFTOP RENARD VS. RENARD FIGHT, GUYS.
LOOK AROUND, LOOK AROUND AT HOW LUCKY WE ARE TO BE ALIVE RIGHT NOW!
They agree that theyre both in a tough spot with their allies all gone.
Further, neither wants to go down for last seasons North Precinct attack or Bonapartes death.
WhenaRenard returns downstairs, everyone worries that Nicks dead and this is Realnard.
Renick insists its him, but as Monroe points out, Thats exactly what Renard would say.
So Adalind asks him a question only Nick would know: Where did they first kiss?
Renick side-eyes Eve before answering: at the table in his loft.
Renicks bonafides established, the team still has to break the news that he might be stuck like that.
But hey, did you forget about Diana?
Adalind and Nick hug as Diana looks on, and its hard to tell what shes thinking.
I want a pony?
Real Renard, meanwhile, staggers home, where a man lies in wait to ask how it went.
I tried to tell you, he says.
You chose the wrong side, Sean.
Its Meisner, and he looks mad!
Okay, I cannot emphasize enough how much pure enjoyment Oh Captain, My Captain provides.
Lets hope this momentum continues as the show returns to its monster-of-the-week roots.
