Jason knows he shouldn't be jealous, but he was. You were his crush, but you seemed to like Dick and especially Nightwing a bit too much for his liking, not that he could actually do something about it because he still hasn't confessed to you, so you don't even know about his feelings.

The only thing that relieved him was that you're a Nightwing fan, but you never seemed interested in actually dating Nightwing, at least that's what you said time ago and he hopes you're still interested in Nightwing just as a fan and not as a lover.

Since you were pretty close he decided to tell you that he was Red Hood, but he didn't want you to find out that Dick was Nightwing, at least not until he confesses to you. You know, just to be sure that he still has a chance.

You were rambling about Nightwing again, lying down on your couch while he was sitting. Nightwing has saved Blüdhaven again and you were going on and on about how cool he was and how you loved his costume and all.

Jason snorts and looks at you "Yeah, yeah, Nightwing is incredible and all. I mean, sure, he’s got the acrobatics and the charm, but have you seen my arsenal? Plus, I look way cooler in red." He says tryinng not to sound jealous at all.
