After shopping in town and training afterwards Garfiel was settling down for the night in his fancy mansion room looking at the brand-new socks he bought. They were thickly knitted to protect him from the cold, they were orange and white which matched his own body. Garfiel had a giant smile on his face as he rolled around on his bed taking his socks on and off and enjoying the way they felt.

"These are the nicest socks I have ever worn; I never want t' take 'm off"

While Garfiel was rolling around he had a sudden desire for a drink of water, so he got up and walked out of his room and into the kitchen where he stepped in a puddle of water near the mop.

"….. FUCK WHO LEFT TH' WATER ON TH' FLOOR, AHHHHHHHHHHHHHHHHHHHHHHH!"

In a fit of rage Garfiel started flinging kitchen supplies around the kitchen and blowing holes through the walls with his fists. Eventually he loses all control and turns into his beast mode with the socks expanding because they are so great. jumping through the 3-story tall mansion and through the roof and out towards Arlem village.

The citizens of Arlem wake up from the sounds of trees falling as Garfiel sprints towards the village in a fit of rage. When he finally comes into view, they all start screaming and trying to evacuate as fast as possible.

"AHHHHHHHHHHHHHHHHHHHHHHHHHH"

"WHAT THE HELL IS THAT THING!"

"RUN ITS GOING TO KILL US"

"SOMEONE GOT MY FUCKING BRAND NEW SOCKS WET, AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH"

Garfiel pounced on the citizens who were all fleeing crushing some of them and started flailing his arms around shredding their bodies into pieces of flesh and bones. Some of their blood and flesh got on his socks as he was killing them all which only got him more pissed as he started tearing apart the dead bodies and destroying all the homes.

Roswaal seeing all the destruction checks his book and realizes that it has been changed and flies over and hits him with a six fold al goa and turns Garfiel into ash. Besides his socks which were magic proof and shrink back to its normal size.

While this all was happening Petra was standing in the pantry in the kitchen with a giant empty bucket of water giggling as she was the one who spilt the water on the floor. Right after Roswaal finally kills Garfiel she steps out of the pantry and her hair turns silver and her forehead becomes the size of a landing strip.

Turns out Petra was Pandora all along and after magically painting everyone's in the mansions face, she dries up the water on the kitchen floor she teleports away off to god knows where in search of her next adventure.

When Subaru wakes up and sees all the destruction and learns of Garfiel's death he kills himself, resetting everything, and leaves a glass of water on his night stand so it never happens again.
