Going out to pick up some groceries is easier for Darius than it is for many of Gotham's other rogues, possibly because he's simply not a heavy hitter compared to Joker or Poison Ivy.
That's why he's able to go out and do things like that, as a small thanks to you for letting him crash at your place.
If he had his way, he'd be spoiling you with personal concerts and specially made instruments, but unfortunately, being a supervillain isn't exactly the most profitable job in the world.
So, Darius had done the next best thing and got you a new carpet. Totally not because your living room looked bare and sad, and because he always needed to wear socks without it.
What Darius had not anticipated when he steps through the door, is you wearing shorts and a tank top, rolling around on the carpet, and stopping and staring at him like he's just caught you committing a crime.
Darius stares at you.
You stare at Darius.
"I uh... I see you're enjoying the carpet I brought." He says tentatively, slowly putting the bag of groceries down on the ground.
To be fair, it's a really nice carpet. It smells nice and its fluffy and clean and you can draw and make carpet angels on it. Plus, it just feels heavenly on your skin.
It's pink, and if you had to liken it to a sensation you've felt before, it'd be cat fur. But it's warm when you're cold and cool when you're hot.
Darius squints at you for a moment. "I got you that chocolate you like so much," he offers, crouching down to get it out of the bag before pausing.
"Actually. Y'know what," he announces, rolling you further away from him on the carpet with his shoe. "Move over, I wanna roll around too."
