When Kurt and Loki arrived from their flying lesson to DADA, Blaine was already there, sitting in a back seat with his hair covering his forehead and eyes. Kurt walked quickly to the back of the room, followed by Loki, and both sat in front of and next to Blaine. "Blaine, are you okay?", said Kurt, with curiosity and concern in his tone.
" 'M fine," Blaine mumbled.
"You're sure?", asked Kurt. "You don't have a headache or anything?"
"No, I'm good", replied Blaine.
Kurt arched his eyebrow, and was about to comment back that Blaine *wasn't* "good", but Professor Castiel entered the room, and announced that class was starting.
By the end of Defense against the Dark Arts, Kurt was almost bouncing in his seat with anticipation. They had been learning about trolls today, but because he and Loki and Blaine were sitting in the back of the classroom, Professor Castiel hadn't called on them at all. When class was over, Blaine, Kurt, and Loki got up, reaching the door slower than the other students. When they got to the door, Blaine tripped and nearly fell.
"Okay, Blaine, seriously, what- what's going on with you?", asked Kurt.
"Umm...", said Blaine. He paused for a few seconds, then said, "Well...it's probably better if I showed you." With that, he walked off to an empty classroom, with Loki and Kurt following him. When they were inside, Blaine shut the door, then spoke. "So, um, you know how I was practicing the Incendio charm at lunch today? I was practicing it in Study Hall, and, um, this happened." He reached up to his face and pushed his hair out of his face, revealing his forehead, eyes, and eyebrows.
Kurt felt his expression changing from curious to a mixture of horrified and amused. Blaine's eyebrows had been partially singed off, making him look like he had two half-eyebrows. Loki was snickering, and Blaine's face fell. "Is it that bad?", he asked.
"Yes," said Loki. "It's that bad."
Blaine's face fell at Loki's pronouncement, and Kurt decided that Loki was going to have a lesson in tact after dinner. "Well, I'm sure some girl in your dorm would be able to draw in your eyebrows," he said, in an attempt to cheer Blaine up.
"Madam Pomfrey gave me a hair-regrowth potion when I went to the Hospital Wing today," said Blaine. "So I'd just need it for tonight."
"I'll go ask Mercedes," said Kurt. "She owes me one for her recent makeover."
