Ron still in a dress would normally be enough to have Harry fighting mirth. Again. But Hermione's shaking and blank look really cut through any amusement, and he gave Ron a quick look and then looked back at Hermione.
"We don't have to right away. . . you can take a bit of time, Hermione," he offered, quiet and awkward. He put an arm around her shoulders, squeezing quickly to try to offer a little comfort. Inept or no.
Hermione was focused though, and both boys found themselves ushered off to start work on figuring out how to destroy the Horcrux. Harry kept it wrapped, but just having it on him was already starting to make him feel tense, and like his skin was crawling. He hoped they sussed it out quickly.
