Lady drags in a full length mirror into the shop and puts it on a wall and sighs

Lady: There we go. Tired of going into that disgusting bathroom to do my makeup. Maybe this will help.

She leaves upstairs while Dante walks in whistling until he sees himself in the mirror

Dante: INTRUDER!!

Dante runs at the mirror and crashes into it, knocking himself out.

Dominic runs in and sees his brother on the floor unconscious

Dominic: Oh my god! Dante! What happened?! Who did this to you!!

He then sees himself in the mirror

Dominic: Did you do this?! YOU SON OF A BITCH!!

Dominic runs at his reflection but knocks himself out crashing into it

Trish: Oh my god! What happened!!

Trish sees herself in the mirror and yet again...

Trish: MOTHER FU-!!

She knocks herself out just like the boys did. All three of them were on the floor unconscious.

Dante. The one who defeated Mundus

Dominic. The one who prides himself on being smarter than his brother

And Trish. The demon who now weilds the legendary Devil Sword Sparda.

And all anyone can say is..

Lady: WHAT THE FUCK HAPPENED?!
