Tara's eyes were sad, as she replied softly, "you're not a Slayer in this classroom, Buffy. You're a student. You're my student. You're my responsibility. Beka won't stop you from patrolling - she cares just as much about protecting people as you do. And she can protect herself. I think you need someone you don't have to be responsible for. I want you to have an hour - even an hour - where you're not a big sister or a big hero. Where someone will stroke your hair, and take your worries away. Even an hour."
