Whoah. A love beyond time???? Holy... the question is reincarnation or just astral? *BTW I suggest listening to a song called "Ancient Souls"(which I think is by Gabrielle Angelique) if you ever decide to explore that 'verse (heck it might even fit with “Lips of an Angel” considering it’s lyrics). It's been a song that has been a bit of a touchstone in some of my more emotional moments having to do with relationships (and has spawned a MAJOR ballet from me if I ever had the money to produce one >_< ). I would say it's a "soulmate" song (where the soul is calling and constantly missing each other until the end of the song). One phrase of the song (it's said in whispers) is "her heart is old, it's light is lost, she wants to be completed at any cost." and honestly that feels like our Lois here (at least in the verse you just started and the one you just described as a possible one).

If you're interested I'll try and post it to yousendit and send you the link.
