Coldwest reincarnation AU?
1 - they always start out fighting. ALWAYS. Sometimes this is in the ‘opposite sides of a war’ thing; sometimes it’s in the ‘you snubbed me in kindergarten and I’ve never forgiven you’ sort of way. There was one lifetime where they seemed to hit it off initially. That was the lifetime in which one of them was a spy for the other side. It was very unfortunate and ended in mutual murder.
2 - They tend not to get together until the dreams of their past lives start haunting them. They never get together because of the dreams, but it’s usually what makes them look each other up - or, if they are already acquainted, think of each other differently.
3 - Iris’ favorite past life was when she rode the elephants of Hannibal and Len flipped her off from behind a Roman infantry helmet. She took him prisoner, and brought him back to Carthage with her when the call to retreat came, and they were married within a year.
4 - Len’s favorite past life is the one where they’re both pirates. No real reason. He just likes pirates.
5 - This time around, they start life off fighting over Barry. It’s hilarious to everyone involved, but somewhat awkward when Barry ends up discovering that Mick is his soulmate-reincarnate about a year or two into this escalating fight. This amuses even more people, and causes Iris to declare that if HE gets a Rogue and CISCO gets a Rogue and even CAITLIN is dating a Rogue now (Shawna doesn’t know how she got in the middle of this), then damnit she’s going to get herself a Rogue, too. Len is not asked his opinion about this, but that’s okay.
