Claudia watched in uncertainty as she seemed to focus on what was, apparently, Christina. She didn't speak, letting H.G. take her time and try to figure this out. "No," Claudia shook her head at the idea of her losing her mind, "I doubt that." At least, she seriously hoped so anyway.
"Uhh...I don't think so? I don't really know. Probably not." she frowned. "She's touching you...? Is she talking to you? What's she saying?" Maybe if she had the invisible child's dialogue to her mother to go on, Claudia could help find an explanation for this that didn't involve H.G. losing her marbles.
