Regulus' reaction would have just frustrated Sabrina some other time.
At the moment however, she was just amused. And wishing she had some idea of what was going through his head. The questioning look in his eyes was a cross between doubt and paranoia, which she could probably handle as long as he didn't get violent with her. Salem was already regarding him with a wary eye, and Sabrina could tell the familiar was getting ready in case he needed to pounce on someone.
She would have rolled her eyes if she wasn't still feeling half dead herself, instead she closed her eye and waited.
"You probably shouldn't push yourself to move all that much yet," she advised, aware he most likely wouldn't listen to her.
She watched him pushing himself to a standing position, debating sending Salem after him on the off chance that he tripped over his own feet or something equally graceless. Keeping quiet and sipping her water while he opened the doors and got a good look at what was outside, she carefully got to her feet and looked around the lobby for an actual chair to sit in.
No matter how long she was here, she would never forget her own arrival disorientation.
She'd been the bearer of the 'you are here' bad news to quite a few people recently, trying to spare them from the same sense of 'wtfuckery?' she experienced. This time was a little different.
She got the sense that nothing she said would appease Regulus.
"You're in a haunted hotel that drags people in from various across dimensions and time periods. The hotel occasionally takes us on trips to different places and times. There are ghosts here, but for the most part they leave us alone. Occasionally they play pranks. The hotel is supposedly somewhere in Scotland, but nobody can say where for certain," she revealed, doing her best to cover all the necessary bases. "There's no room service at this hotel. You'll have to make your own food or rely on one of the many people who constantly make extra food. Otherwise, you can't leave, but the hotel does send people back to their time sometimes. I recognize that you probably won't believe me or think I'm pulling your leg, but I promise you that I'm not."
