Lavender

"This is HC7. It's a mild pain killer and growth stimulant, more commonly known as Lavender. We don't make a habit of using it because of its unpredictable side effects, but in this case we're making an exception." When Katniss spends a night in the hospital of D13, she certainly wasn't expecting such a... passionate encounter with someone who she thought hated her. Hijacked!Peeta.
