Tim had never been jealous before. Not with any of his previous relationships or any of his crushes. He didn't mind when it was them.
But you? He hated people even looking at you with interest. He never told you, or reacted much outwardly. On the inside, though, he wanted to punch something every time someone would hit on you. He didn't really know why he was so jealous and possessive, but he just was.
He'd never admit to how jealous he really got. No, he would just count to ten in his head and make sure to breathe so he didn't murder anyone. And he liked hanging out with your mutual friends from school. He was a friendly guy, and he sometimes had friends from his vigilante life in with the mix. You'd met Conner before, and the two of you got along really well. A little too well.
Conner just had a flirty personality. It didn't mean anything, and rationally, Tim knew that. He really did try, anyways. But it still made him a little jealous when Conner would blatantly use pick up lines on you, or flirt like you weren't Tim's partner.
Tim tugged on your sleeve, just a bit, trying to get your attention. You were in a conversation with Conner, and Tim was desperately trying to get you to pay attention to him instead. He was your boyfriend, therefore he deserved your attention more than that idiotic clone Tim occasionally called his best friend.
Tim wrapped his arm around your waist, trying to not-so-subtly tug you back away from Conner. You could talk to literally anyone else and Tim would be fine with it. Anyone but him.
"Hey babe." Tim tugged on you again. "C'mere." He gave Conner a too tight smile, trying not to be mean to his friend. He knew the super clone wasn't trying to steal you away, but that didn't make the uncomfortable feeling in his chest go away.
