Jason had tried to convince Dick to bring everyone to a haunted house for Halloween for weeks before the 31st. After relentless nagging, Dick agreed.
You and Gar were by far the most easily scared people on the Titans. It took Jason and Rachel $10 to get you to come to the haunted house with everyone else.
It was already dark when you got to the haunted house, all dressed in your Halloween costumes. Jason was ecstatic and grinning as was Rachel. Dick and Hank thought it was the most stupid thing ever and Dawn was trying to reassure Gar that it would be fine.
Five minutes into the haunted house and you and Gar had somehow ended up in front of everyone. Gar was holding onto your costume for dear life while pushing you forward.
The walls were decorated like any other haunted house, with spiderwebs and fake blood painted onto the long corridors and litter scattered on the floor. Actors dressed up as the most horrible beings ever were waiting behind each corner, ready to jump out and scare you.
