Willow follows his gaze to the tower, and quickly looks away, frowning. "I-I dunno. Usually it just plays out the way it really happened. A portal opens just under the tower... Buffy jumps into it to save her sister, and the world, and we find her, and I wake up."

"We couldn't save her," the butterfly adds sadly. "We tried, but we didn't see what was happening quick enough to stop the portal from being opened in the first place. There was a lot going on on the ground too."
