Alfred had ceded the right of way to her in case there was any sort of de-cursing she wanted to do before she went in, or something. Not that he had experienced anything in the cabin that would lead him to believe it was cursed, but he hadn't experienced anything on the ship in general, either (aside from the initial incident when he'd tried to open the chest), and the Ministry had more or less condemned the whole thing, so. There was no telling where they drew the lines, exactly.

Nothing happened when she walked in, but her wand launching itself across the room after she cast that twitching spell didn't seem particularly optimistic.

"What's that mean?" Alfred asked, shuffling in to stand just inside the doorway. Hopefully the answer was relatively tame and not something like it means you've got magical Spanish flu now, because this place is super-cursed.
