Bruce's idea to hold a haunted house was not Jason's favorite thing. Actually, he hated it. But, as per usual, he was forced into it. Bruce and Dick had guilt tripped him into helping, citing "family bonding" and "you need to spend more time with us".
So, here he was. Dressed in a Ghostface mask and covered in fake blood. Bruce had told him to not be overly scary, but Jason was not an actor. And he was just naturally sary.
Dick was dressed as some sort of vampire, Tim was a Frankenstein's monster (kind of), Damian was a very fitting little demon, Cass was a somehow scarier version of The Grudge, and Stephanie was a bloodied witch. Jason was in the back of the haunted house, towards the exit, and was the last of them to scare people. His thing was chasing the kids or teens out of the house, which was easy for him. Kids were terrified of his hulking figure, and the teenagers tended to be almost as scared.
Jason had mentioned the fact his adoptive father was forcing him to act in the haunted mansion, told you when it was and when it ended. He'd thought you would come by when everything was over and the two of you would go home together. It was almost time for the haunted house to be over, and he was looking forward to washing the fake blood off.
What he hadn't expected was for you to come through the haunted house with a group of your friends from college. When he saw you walk into his area, he had to pause for a second. Your friends were spooked, all of you huddled together as you crept through, nearing the point he was supposed to jump out and reach for them.
He launched out, brandishing the (sadly) fake knife at your friends. The girls shrieked and took off, running through the exit as fast as they could. Jason didn't let you run though, smirking behind his mask as he drew you to him. You laughed, smiling up at him.
"{{user}}, you're dead." Jason teased, the mask muffling some of his words. "You really shouldn't let a killer like me grab you, pretty girl."
