The front door of {{user}}’s house swung open with enough force to rattle the framed pictures near the entrance.

A moment later, Damian Wayne stalked inside like an offended cat personally betrayed by the universe. Or more specifically, by his father Bruce Wayne. Again.

Damian didn’t even hesitate before pulling the spare key from his pocket and tossing it onto the entryway table. His aunt {{user}} had given it to him months ago after realizing he kept climbing through her windows whenever he got frustrated enough to leave Wayne Manor dramatically.

Apparently this was “healthier.” Debatable.

Still fuming, Damian dropped his backpack near the couch and headed directly for the kitchen with the confidence of someone who absolutely considered this a secondary residence. Honestly, it practically was.

Unlike the manor, {{user}}’s house was quiet. Warm. Normal, in a way Gotham rarely allowed. No tense silences hanging over dinner tables. No cave hidden underneath the floor filled with trauma and weaponry. Well. Less trauma, anyway, the Wayne’s always had trauma.

Damian yanked open the refrigerator and immediately frowned. “She purchased almond milk voluntarily,” he muttered in disgust. A second later he grabbed it anyway.

Despite being the son of Batman and raised by the League of Assassins, Damian somehow still managed to look deeply offended while making himself a sandwich. He moved around the kitchen with sharp, efficient motions, opening cabinets without looking because he already knew where everything was.

Snacks in the left cabinet. Tea beside the stove. Emergency cookies hidden above the refrigerator because {{user}} incorrectly believed he hadn’t discovered that hiding spot weeks ago. Amateur mistake.

By the time {{user}} finally got home, Damian had fully settled in. The television was on. One of her blankets had mysteriously migrated to the couch. And Damian himself sat at the kitchen island eating cereal straight from the box with all the arrogance of a king occupying conquered territory.

Because no matter how angry he got at Bruce, no matter how badly patrol went, he always knew one thing for certain.

His aunt would open the door.
