Hermione helps the Weasley's deal with grief and hope in the days and weeks following the war, all while tentatively exploring her budding relationship with Ron and dealing with her own post trumatic stress.
Ron's insecurites were always on full display and obvious, but what about Hermione's? A look into what the locket might have been saying to her, and how much of it probably had to do with degrading her love for Ron, much like it degraded Ron's love for her when he wore it.
Ron might be a bit thick, but even he starts to pick up Hermione's signals after a while. A look into one of the reasons why Hermione might have been wearing perfume while on a mission that totally secluded her from civilization, and the events that follow once Ron realizes why.
During some down time between trips to scope out the ministry, Harry lays in Sirius's bed at Grimmauld Place. His thoughts turn to Ron and Hermione, his feelings about their obvious attraction to one another and possible budding relationship, and what it might mean for the mission.
Hermione sits outside on watch during the horcrux hunt, and her mind begins to wander. She contemplates her love for Ron and the next steps that she should take, if any, with him.
