Danny/Maka. My friend and I watched some Season 1 episodes and "Triborough" and "Till Death Do We Part" were one of the episodes we watched. I saw Danny and Maka together and I thought that they have good chemistry together despite the lack of cases together or being onscreen together.
But Flack/Aiden (newly named as Flaiden by us Flack/Aiden shippers) will always be my number one ship.
I think that Danny and Lindsay would be cute, because with everyone else, you don't get the sense that one has a crush on the other, but with Lindsay and Danny, other characters on the show, such as Sif acknowledge the fact that Danny has a crush on Lindsay, and he is always kinda making fun of her, and callling her 'Montana', which kind of goes with one type of the stereotypical crush, that the person you kinda of give nicknames or are a little mean to those who they have a cruch on
Mac & Stella kind of seem like a married couple (couple years married) to a degree, like they care about each other, have each others back, but seem to have a different relationship than a brother-sister thing
