Hermione hadn't needed to be present to charm the parchment for quite awhile now. Still she felt an ownership of the task that drove her to be present at each meeting barring extenuating circumstances. Besides her presence allowed Seamus to focus more on greeting individuals and sharing the rules without having to focus on the parchment itself. It also allowed Seamus to start the meeting while she hung back to catch any stragglers that arrived late. Hermione honestly didn't mind helping. It showed that she was on equal footing with everyone, not worth the hero worship that some had tried to saddle the trio with that thankfully had waned quite a bit over the years.
She listened quietly as Dean spoke. She knew of his nightmares. Everyone at Shell Cottage had been aware. Each of them had baggage from Malfoy Manor that they'd had to deal with. Not that she attributed it all to the Manor as there were so many other things that happened during that time frame. Being prisoner there was only a part of the picture. In fact, for Hermione it had been the days after Ron had left that had been hardest. Not knowing whether he lived had been horrible. In fact those dreams had begun to creep back in over the past few months. Uncertainty about where they stood bringing everything up again in her subconscious.
"Does the potion help?" she asked out of curiosity. She didn't need one because she never knew when her's would appear and she didn't want to chase away the good dreams.
