I compiled a list of AU/crossover couples I think would be interesting to see as couples. I really only did this with shows I watch so there are alot of characters shipped with multiple people. I also want to apologize for not including interracial and same-sex couples. I have nothing against them I just wasn't thinking of them when I made the list. I would like to know what you think about my list and which characters from crime and medical shows you would like to see as crossover/AU couples.
Here's my list:
James Wilson (House) and Stella Bonasera (CSI: NY)
Aaron Hotchner (Criminal Minds) and Stella Bonasera (CSI: NY)
Mac Taylor (CSI: NY) and Lisa Cuddy (House
