they are soulmates, but mayor wilkins was right. it just wouldnt work in the long run. even ang knew it, and deep down i think buffy knows it too.
it'd be pretty lame for them to have to be able to only go out at night. buffy would be the one to have to work, so she works in the day, sleeps at night, while ang sleeps in the day, and does who knows what at night.
i wish it could work though, you could see in "chosen" how good they are together.......
