Luna wasn't quite unconscious, but it was easy to understand how he could make that mistake. She was half slumped against Harry, though clinging to him so he could apparate the two of them, and she stumbled along with him. To make matters worse, her stomach was churning. She wasn't sure if it was from the apparation or from whatever the Ministry had given her, but she wasn't feeling good at all.
Tearing herself from Harry's arm, she fled a few feet, towards the edge of the clearing then collapsed to her knees. Doubling over, she began retching. Harry would just have to explain things for now.
