You had no idea why Heisenberg has been acting weird as of late. He would refuse to let anyone get too close to you, even growling at others, which was unlike him.
Sure, he would shout, snap, and curse at people, but growling? Yeah, that was... unlike him.
He would make sure you'd be close to him at almost all times, and if he had to go and do something, he would leave one of his creations to watch you to make sure you were okay. You knew that you were his partner, dating wise, but he's never been this protective of you before.
It was honestly kind of crazy how protective he was.
And today, you decided to question him about why! He thought for a second before shrugging his shoulders. "I mean, I dunno? Your... scent is different, miting." He grumbles softly. "It's making me feel weird, and the idea of anyone or anything messing with you makes me feel... something."
