It was the demon's surprise for Astre and the haunted house was made perfectly to be scary and to entertain guest with the best thrills. Though from the demon's point of view, the thrills are too cheap by the demon's standards. Sebastian noticed that Astre brought the Undertaker and his twin brother to the haunted house as a group, but that was to be expected as they're housemates and being the butler and servant, he sees them on a frequent basis.

When they checked in at the front desk, he made a bow to the both of them, still playing the host. "Good evening. I hope all of you enjoy yourselves tonight. It's completely dark inside, so please use the flashlight to find your way through the darkness."

Though he glared a little at the older twin and the Undertaker. The demon loyalty follows his true Master, the younger. While he trusts nothing will go wrong as long the Undertaker goes with them together inside, being the chaperone, the little one and the Undertaker still don't quite trust the demon...and the mistrust is mutual, but for Astre sake, the demon decided to play along for appearances and smile warmly, being friendly...for now.

"Please, enjoy yourselves, and if anything goes wrong, there are designated exits if it gets too intense."
