Since the DA meeting, Ron was walking with Luna to the Hospital Wing. An accidental elbow from Neville had given her a sore rib. Both were concerned that Harry hadn't turned up to help Ginny teach the Boggart-Banishing spell. When they got to the door, Ron tried the knob. Oddly enough, it wouldn't turn. Immediately, Ron grew suspicious. He turned to Luna and asked, "You don't think something happened to Harry in here, do you?"
"If it's locked, and it's never locked…" Luna's voice trailed off as her expression turned to a rare look of concern. She rubbed her side with a wince, and looked down the corridor. There was no sign of anyone at all down the illuminated expanse of brick.
"We could get in," she mused, "and there's no one here to see it."
"Right," Ron nodded, and pulled out his wand, "Alohomora!" There was a click at the sound of his short, firm vocalization. Luna reached out, and turned the doorknob successfully. She gave Ron a congratulatory smile before pushing the entry open. It was, for once, empty but for several students either unconscious or sleeping. Ron couldn't quite tell which, but he was fairly certain that if someone surprised Harry quietly, or more likely gave him something he wasn't supposed to have, it would explain Harry's absence from their meeting. Both of them quietly entered, and looked around. Nothing seemed out of place, but Ron was not ready to give up just yet. "D'you think, Luna, that Crabbe and Goyle could've slipped Sleeping Draught to Harry?"
"Sleeping Draught? I've no idea, but it couldn't have been Crabbe and Goyle," Luna shook her head.
"Why not? They're thick with Malfoy. If he suggested it to them, they wouldn't have even asked why." Ron stepped to a cabinet, and found some Bruise Balm. Handing it to Luna, he rummaged through the rest of the contents to find that there was no Sleeping Draught inside.
"No Sleeping Draught?" Luna guessed.
"No," Ron conceded, "but they could've taken the last of the bloody stuff."
"I don't think so," Luna tilted her head to the side, "Malfoy would have been involved completely. He wouldn't have trusted them to do it on their own, and there would have been quite the commotion."
"Yeah," Ron frowned, "you've the right of it. Bloody hell, if it happened here, who could tell?" They exited the Hospital Wing, even more worried than before.
"We should find the others. I'm sure everyone else noticed Harry's missing," Luna pointed out.
"Right," Ron muttered with a nod, "let's go." Ron stuffed his wand back into his sleeve, and turned back to Luna, "did you put the stuff on?"
"Oh," Luna looked down at the petite jar in her hands, "no, I suppose I'd forgotten. Thank you, Ron." She turned back into the Hospital Wing, tossing a "I'll find you later to help" over her shoulder. Ron was left standing alone in the corridor while the worst situations possible ran through his mind. He took a deep breath, and turned to find Hermione. She always knew what to do.
