And because he didn't, he had a front row seat to a betrayal deeper than any that had come before. One worse then Hermione leaving him. Worse than Blaise keeping her return a secret, or keeping her whereabouts for the two years prior a secret. He watched, as though petrified, as Blaise's mouth covered Hermione's. Watched as Hermione's small hand reflexively gripped the front of Blaise's shirt. Watched as Blaise set aside the unopened vial and slid both hands around to cup Hermione's ass (he seriously considered burning his eyes out of their sockets, just to keep the image of Blaise's hands where his own used to rest out of his brain) and pull her towards him, causing her dress to ride up higher. Watched as Blaise slotted their hips firmly together with a contented sound. Watched as his best friend's hands slid up Hermione's back, tangling in her hair. It wasn't until Blaise groaned into her, tilting her head back further in order to kiss her more deeply (dear God was that tongue?) that Draco turned on his heel, and walked away, completely numb. He didn't see Hermione push Blaise away, didn't hear anything of the fight that followed, as he retched up everything in his stomach in the bathroom toilet, tears he hadn't shed in years streaming down his face.
