It took a moment for Higgs to concentrate enough to realise that Lydia had actually opened the door and was now standing in front of him, her hand against his arm, which Higgs brushed off almost automatically. "I'm sorry," he said before anything else could leave his lips. "I--" But there wasn't really an explanation Higgs was all too sure he could offer. It was borderline like coming to someone after a bad dream. Except his dream had confronted him in the street. "I saw a boggart," Higgs said finally and followed the statement with a laugh that was so dry and humourless it would have startled him if Higgs had been in a position to judge such sounds right now.
"It's stupid, I'm sorry," Higgs offered again, but despite how much he wished he could just leave, just pretend this hadn't happened at all, his heart was still racing, the sounds were... better, but still there. At least Higgs' breathing had evened out enough that he could actually speak. "Could you just give me some water?" Higgs asked realising his throat felt extremely dry. Not too dissimilar of how it'd feel if he would've spent weeks in a dessert. A feeling he was very familiar with.
