Cho found herself a little stunned by how defensive Marietta was being. She was just concerned, and she worried that at the moment, Marietta herself wasn't thinking clear enough, and didn't know what was best for her mother. "I mean a grief counsellor, someone who can help, someone who knows how the mind works...I mean come on, Marietta, just because we're witches, doesn't mean our minds don't work the same way as muggles! They might be able to suggest something that doesn't involve changing her mind the same way an obliterate does! What if you did it wrong, and you've damaged her more than done her good?" She sighed, not liking the expression on Marietta's face at all. "Honestly, sweetie, I don't think you're thinking straight right now, and it's okay, no-one expects you to." She sighed, thinking back to Seth again. "No-one does when they've experienced losing someone they love."
