[Buffy & Faith] Willow is here. She doesn't know that Tara died. Or that we fought the First and Sunnydale is now a crater.
Or, you know, that she went wacky and tried to end the world. I might leave that part out for now.
[Tara] So... Willow is here from an earlier point in time than you. She doesn't know that you two were reconciling or about the other thing I told you that happened.
