Thinking about Cold and Smitten but they're both into Fury but for different reasons. Cold's into Adversary!Fury and Smitten's into Tower!Fury.
Cold finds Fury amusing. He loves seeing her get so angry over him denying her the fight she desperately wants. He's curious about how much further he can push her buttons and how much pain she can inflict on him by unraveling him (you could say he's a masochist). But he eventually realizes that behind all that power and anger, Fury feels numb and empty. She wants to feel the spark she once felt but can't get it back anymore. She had lost her ability to feel...just like him. And once that realization hits, that amusement Cold had before is replaced with sympathy and understanding. As apathetic as he may be, he doesn't like to see someone else go through the same emptiness that he felt.
And I know that Smitten doesn't show up in Tower!Fury (Ok maybe he does for a split second but it's purely for joke reasons) But I remember reading this fic on AO3 called Mortality (check it out here), where the two of them interact. And that got me thinking...
Smitten is absolutely enamored by Fury. The dominating power she possesses, her beauty combined with her gory desecration, and even her poetic speech filled with hate and anger. He can't help but see her as the goddess she once was. At first, Fury thinks he's mocking her. How dare this pathetic little voice finds her beautiful even after she had been stripped from her godhood. Of course, she makes him go through the same torturous unraveling, but even so, Smitten's love is powerful enough for him to survive through it all. And once Fury stops, she sees how sincere Smitten is and not only feels bad, but also wallows that she misses the praise and worship she once had from being the perfect goddess. She feels like she is nothing...but she is still everything to him.
Eventually Cold and Smitten both realize they're into the same princess (somewhat) and find it almost baffling. Smitten questions how someone as heartless and emotionless as Cold be into someone full of raw anger? Especially after denying her everything she wants? Cold thinks how someone as naive and loving as Smitten could be into someone who wants him dead? Especially after she became a more gruesome version of her perfect ideal self? But the more they think about Fury and their feelings towards her, the more they slowly understand each other. Perhaps Cold isn't as heartless as Smitten thought he was. And perhaps Smitten is emotionally stronger than Cold thought he was. In a way, their shared affection towards Fury brings them a little closer.
