In the Nurse's office, the school nurse examines and bandages Marinette's bloody nose.

Nurse: It's nothing too serious, Marinette's just experiencing some minor blood discharge from her right nostril.

Marinette: See, Barry? I told you, I'm fine.

Nurse: Now, how exactly did this happen?

Marinette: I just sneezed, and all of a sudden, my nose just, gushed blood everywhere.

Nurse: Mmm-hmm, and when did you first experience these nosebleeds?

Barry: She said it was from when
she tripped coming to class, the day before yesterday.

Marinette: "Yeah, it was after lunch that day, I went to the girls room to wash my hands, and just as I was rinsing the soap off, I had to sneeze."

A flashback shows Marinette sneezing and blood leaking out of her nose.

Marinette: "And that's when I noticed a trickle of blood leaking out of my nose. I was honestly worried, because this had never happened to me before. It wasn't that bad, but I knew had to clean it up before anyone would notice."

Nurse: Okay. Well, Marinette, I suggest you try to avoid any blunt force to the nose, and you should be healed in a few days.
But for now, I suggest you go home and take the rest of the day off.

Marinette: Will do, and thanks Barry.

He nods and walks out. As Barry walks out of the office, he ponders to himself. Before checking his jacket pocket, which holds a small vial containing Marinette's blood.

Barry (TB): "This can't be possible.
I mean, what are the odds that Marinette starts getting nosebleeds, exactly two days after I punched Ladybug in the nose?
That can't just be a coincidence. I mean, there's no way to sugarcoat it.
The only explanation, is that Marinette is Ladybug!"

Barry furls his brow.

Barry (TB): "Oh c'mon, Barry. That's nothing but speculation.
You need more proof, looks like you're gonna need to put your forensics skills to the test on this one."

Barry walks back to the group, their expressions are tense and nervous.

Barry: It's all good, everyone. Marinette's gonna be just fine.

They all sigh, relieved.

Mylene: Thank goodness.

Alix: That's the first time something like this has happened to Marinette.

Alya: I know, as clumsy as Marinette can be sometimes, something like this has never happened to her.
The girl once ran into a wall, face first! And she walked it off, like it didn't even happen.

Chloe: I know this isn't my style, but I'm actually worried about Dupai-, Marinette.

The group gasps, shocked.

Nino: Dude, this is a first.

Sabrina: Yeah, Chloe never addresses Marinette by just her first name, ever!

Juleka: (Mumbles) That must be how serious this is for her.

Rose: This day is full of surprises!

Barry: Don't worry, Chloe. The nurse said it's nothing too serious, Marinette's going to be fine.

Adrien: Yeah, and besides, considering how tough Marinette is, there's no reason to say she won't be fine after this.

Chloe smiles reassured, and hugs Barry.

Alya, Rose, Sabrina, and Mylene: Awww!

Juleka: Awesome.

Chloe: Thanks, Barry.

Barry still hugging Chloe, just smiles. And notices Adrien, who knowingly gives a satisfied nod.
Barry nods to Adrien, and let's go of Chloe.

As she and Sabrina walk away, Barry pulls Adrien to talk in private.

Barry: I have some surprising news for you Adrien.

Adrien: Lay it on me.

Barry quickly pulls Adrien to the locker room.
