This is absolutely and utterly gorgeous and amazing! I love it so much! This pairing is one of my favorite rare pairs and you captured both of them perfectly-- all rough and tumble and raggedy-edged school boys who suck at expressing emotions but really love in their own way. Piers broke my heart and the image of him running with silent headphones made me tear up. And "Missed you?" said Piers, straining at the grip on his wrists as he silently begged his leaky eyeballs not to betray him. "I fucking mourned you, you miserable fucker." broke me into a shattered mess.
Dudley's devotion comes across so well and I love how it's so simple and unadorned. He's just amazing here and the bits about him being completely over his parents' constant whinging is brilliant. I also LOVED his words for apparating! LOL! And the description of Diggle and the image of war-weary Harry coming to spring them and getting harassed by Vernon and Petunia and then Dudley asking him to get them out of there! Oh, that was the most perfect thing. I love this. So, so much! Glorious, glorious work, Mystery Writer. You win at life and I shower you with goodness and candy and blue bells and serenade you with Whacking Day songs!
