"Pardon?" Hannah asked with a puzzled frown at Ernie's strange outburst.
"Sunshine. Natural, direct sunshine to be exact. It's what your potion is missing. It needs to be exposed to sunshine to work," Ernie paused and frowned. "It needs to counter dark creatures and magic and what you really need is a source of light. And what better source of light than the Sun?"
Hannah frowned.

"Something for you to talk to Neville about," he said with a smirk and Hannah blushed. "That way you can stop avoiding him and actually talk."
"Ernie!"
Ernie simply snickered with amusement as Hannah's face turned red.
