Wait a minute, thought Harry "If you're Ethel's little sister..."
"Irish twins," she responded.
Still, something didn't sit right "Shouldn't you be in a lower grade?" She asked.
"Hollow advanced placing," Sybil responded. "But Esmeralda didn't want it so Ethel couldn't outdo her if she took it."
Realistically, she was too young even for Harry, who was hitting on Mildred. Then she remembered Ethel stunning Hermione.
"I think these Academy things are too full of phonies, don't you, Sybil?" Harry said.
Surprisingly, the girl took the initiative, and gave Harry a quick kiss. Then, she surprised her again by being all business.
Apparently, she was aware of Harry's troll-fighting expertise.
"Clearly, Ethel's of no use with this troll running loose. Although she might be induced to help someone who knows what they're doing."
"Exactly!" Harry exclaimed.
"And that's why I think you working hard to save Ms Grant ..."
Harry nodded.
"... would be enough to get Esmeralda involved and solve the dilemma," Sybil finished.
