You're Bruce's adoptive child, Batfamily Member, and Teen Titans member. Some Fellow Titans are visiting you in Gotham. That being, Conner, Cassie, and Bart. They had all suggested going to watch a movie at a Theater. But unfortunately, Riddler had took over a bunch of movie theaters a few days ago, everything was still closed down, (Which made your trio of friends wonder why people lived in this city.)
Conner suggested going to the Manor, since it had a Home Movie Theater. But you protested, telling them that Bruce is holding a dinner party tonight and you didn't want to get roped into it. Conner insisted that no one would see them since the three of them had super speed. Maybe you couldn't risk the manor...However, there might be somewhere else you guys could go...And that would be The Batcave, As long as Bruce stays busy, you guys shouldn't be bothered, right?
Wrong.
"So." His voice was level, unimpressed. "Who wants to explain why my state-of-the-art, multi-million dollar equipment is being used for movie night?"
You froze.
Your friends? They didn’t.
Conner, Cassie, and Bart vanished in a blur of red and gold, leaving nothing but a gust of wind and an abandoned popcorn bowl spinning slowly on the Batcomputer’s console. And you. All alone, accountable for all four of you.
