Rare Pairs Challenge: Day 19-20

Day 19
Some small fandoms this time (ones that I'd personally love to see more fics in), instead of pairs from a specific one.  Use the actual characters, plots, or just the ideas behind them and make them your own.

Banlieu 13 (or D-13/District 13 in English) - Leito is a street rat, parkour expert, doing what he can to help the people in his neighborhood. Damian is a cop that specializes in undercover work (including as a woman).  You can find a summary of the first movie here.  (Paul Walker actually did an American version of this called Brick Houses and the guy that plays the street rat is the same guy that played Leito in the original)
      Does character A go undercover and discover that the criminal they were after is actually more of a Robin Hood, trying to help out his neighborhood that's struggling under horrible conditions?  Does something happen to Character B or a loved one and they reluctantly go the cops to get help.  Does the odd couple find out something fishy is going on with the people in charge and team up to take them down?  Instead of a cop, maybe it's a security guard inside of a corporation, or private security? Maybe the robin hood is a hacker or a cat burglar that gets in over their heads?

Knives Out - Benoit Blanc (Daniel Craig) is a private detective that's been hired to help find a murderer. Ransom Drysdale (Chris Evans) is the spoiled grandson of the deceased with a chip on his shoulder and an attitude as big as his ego.  So, honestly, depending on how much you want to stick with actual canon depends on what you can do with these two.  But it's a great setup for some daddy kink, power imbalance, or other fun kinks you might want to try out (hell, there's an actual photo of Chris sitting on Daniel's lap).
      So, character A is a private detective, is Character B the charming criminal or an innocent person being framed, and what will they do to convince A they're innocent?  Character B is in trouble and hires a private detective to help them out, is there an instant connection or do sparks fly?


Day 20
Quote from the song "Once Upon A Dream" from Disney's Sleeping Beauty, slightly condensed (there was a very moody version done for the movie Maleficent also).  Use part of the quote or just the idea.

"I know you, I walked with you once upon a dream...but if I know you, like I know that I do, you'll love me at once, the way you did once upon a dream"

So, great for any of the supernatural/fantasy fandoms with some dream sharing - is it hot and steamy, soft and fluffy, horrifying, humdrum? Do the dreamers know each other beforehand or are they drawn together because of the dreams?  Is your character a Disney fan and caught singing it by the person they're crushing on?
