Buffy: Episode: New Moon Rising
Oz: I shouldn't have come back now. I just thought I'd changed.
Willow: You have changed. You stopped the wolf from coming out, I saw it.
Oz: I couldn't look at you. I mean, it turns out the one thing that brings it out of me, is you. Which falls under the heading of ironic in my book.
Willow: It was my fault. I upset you.
Oz: Well so we're safe then, because you'll never do that again. But... you're happy?
Willow: I am. I can't explain it.
Oz: It may be safer for both of us if you don't.
Willow: I missed you, Oz. I wrote you so many letters... but I... didn't have any place to send them, you know? I couldn't live like that.
Oz: It was stupid to think you'd just be... waiting.
Willow: I was waiting... I feel like some part of me will always be waiting for you. Like I'm old with blue hair and I'll stumble and there you are. I won't be surprised. Because... you're with me, you know?
Oz: I know. Right now is not that time... I guess.
Willow: No... What are you gonna do?
Oz: I think I better take off.
Willow starts to cry and then they hug goodbye.
