Draco’s mine was running a million miles an hour, already itching to isolate the sole signature and to compare it to the two that he already had. He had no idea what he’d find, but if this was different from the other two he has, then he definitely has great potential to come up with a more solid theory.<br/>“I hope a couple of hours, but realistically it’ll likely take me a couple of days,” Draco admitted, looking at the silvery threads in the vial as he opened the door to his study. It was a familiar feeling to be back with Harry in here, the comfort of their shared routine not entirely out of his system yet. He wasn’t even sure why he had invited Harry to join him in the study, other than having missed having him around.<br/>“It’s a finicky process and I don’t want to ruin the spell, so I’ll have to be careful,” he explain, even if he was certain that Harry already would have some idea of that.
