Buffy & Spike claim each other and Angel must witness, prophecy that includes Dawn

Ok, I read a fic a while back that I have trouble remembering, but here's what I do remember:

- Some prophecy that includes Buffy, Spike and Dawn

- Faint drawings that Spike has to copy and interpret that end up being a sword, a bracelet and I forgot the 3rd item

- Buffy & Spike plan to claim each other (can't remember if it's for love or the greater good), but Angel has to witness the claim and it happens one night when Spike is training Buffy in an old abandoned theater - it's pretty brutal and sexual and Angel allows the claim, but he's hurt

- I think Spike drinks some of Angel's supply of blood and figures out that someone has been lacing the pig's blood with Connor's blood

- The baddies at the end are invisible and look like ripples in water

That's all I can think of, but it was a very long story and I can't for the life of me remember any more details. Help..?

Series starts with "No such thing as coincidences by All4Spike"

Summary: After Buffy beats Spike up in 'Dead things' he goes off in a huff, ends up at Angel's... then there's a prophecy... and Buffy comes looking for him...

I cannot not keep these threads open forever guys, so since the original poster hasn't denied that this fic provided is not the one they were seeking. I will assume it is, and moving this to found.
