You're Not A Monster, Natasha/Bruce
Bruce feels that the Hulk is a monster, an untamable, monster with a love for destruction...
"The sun's getting real low, big guy," Natasha hums, putting a hand out for him.
He slowly takes her hand, relaxing and turning back to Bruce so willingly.
"I don't know how you tamed him," the scientist sighs, leaning against the small woman.
"I'm used to dealing with “Monsters”," she hums.
Natasha sees herself as a monster, someone who has killed more than saved, and she doesn't feel like that will ever change, because that's what she was raised to be...
"You're amazing," Bruce hums as Nat gives some kids their puppy that she just got out of a water way before he could be swept away.
"I just didn't want them to lose a friend," she denies.
"Don't act like that, Nat."
She just walks away from him.
Natasha sees the Hulk as just another side of Bruce, an untamed, but lovable side of him...
The Hulk is destroying a building when Natasha catches up to him.
"Easy, easy," she whispers, pulling his arm back gently.
The green mass looks at her softly, relaxing on sight, and moves away from the building.
"That's it, big guy, the sun's getting real low," she offers her hand again and Hulk actually smiles.
Bruce sees Natasha for her actions now, not then, he knows she's tried so hard to forget about her past, and to make up for it, and that she deserves a break.
"You're not a monster, Nat, you're probably the last person I'd use that word to describe. You're letting your past control you, but ask anyone, you're far from a monster," Bruce insists.
"After everything I've done, I'll never be able to believe that," the red head sighs.
"I'll keep telling you until you do," Bruce grabs her hands.
Neither of them will be able to convince the other, but that will never stop them from trying.
