You know what, no. Tim can have the Batfam emotional brain cell for a minute.
Tim considers the situation and decides that, if things were reversed, he'd be more upset at Danny not telling him there's nothing for him to worry about. And the longer this goes on, the worse it'll get. It's not like he doesn't trust Danny with his life or his secrets (Danny's shown he's good to keep at least his own identity secret enough).
"It sounds like you really love your husband. I think you should talk to him about it. It might go better than you expect. No really," when Danny seems skeptical "If you're talking about who I think you're talking about - and come on I'm the world's other greatest detective, I figured Batman out at like age 8 - he won't love you any less for it. Then you can tell Constantine to fuck off." After a moment "I mean, you wouldn't love him any less if he was keeping something like a vigilante life secret from you, would you?"
Danny considers this. He concedes that he would still love Tim, even if he were keeping a second life from him. Tim... was kind of angling to get Danny to confess first, give him that level of autonomy over his own secrets. But it also gives him a plan B, in case he can't wait.
And Danny takes too long. A week later they're each prepping for a space-ghost mission, and Tim can't stand the idea of Danny being so close but so far, for the extended time of a space mission. And what's worse is that Danny would be there under coercion, when there's no actual risk.
Tim sits his husband down.
"Shouldn't you be preparing for your business trip?" Danny asks
"Yeah, I am. There's something I need to talk to you about before we leave" ('uuuh, I'm going on a different trip from you tho') "Look, Danny, I really should have told you this before but I. Just. I didn't know how to bring it up and by the time I could you'd made your opinions Very Clear. But. I." Tim had a whole speech prepped, but he's forgotten all of it, in the moment. But he does have one of his Red Robin patterned birdarangs on him. So instead he just shows Danny that.
"..." It takes Danny a moment "Tim are you."
"Red Robin. You're cheating on me with Red Robin. Of course."
"I knew it. I knew this was too good to be true." Danny stands. He starts to pace, like the revelations are too much to contain while stationary.
"I'm not cheating on you with the Red fucking Robin!"
"No - no, you said it like this has been a thing for longer. Am I the other woman?? No wonder he thought he knew I was talking about you!"
"Danny will you sit down! I'm not cheating on you, I'm trying to tell you that I am Red Robin."
That actually stops Danny short.
"You." Tim nods. "Are a vigilante." still nodding. "Bullshit" what. "You, Tim Drake-Wayne? CEO of Wayne Enterprises? You'd be more likely to end up on the Fruitloop end of cape-life."
"Rude. I'm not lying though."
"Why would you? You're super rich, you could solve the problems in Gotham financially!"
"Can't throw money at muggers. Or the mob. Or corrupt cops and politicians," ("I mean you can but") "And you can't throw money at interdimensional tornado ghosts hell-bent on destroying the earth."
"I just. I wanted you to know. That I know. Before we leave."
"Yeah. I. Wanted to wait for you to be ready. But. I can't. I can't go up there with you, knowing it's you. Without you knowing it's me. And I can't let you go, not if you're forced to. Not if I can help it."
"Oh. So this. This isn't about you being Red at all. This- This is about me."
"I wanted to let you tell me. I wanted you to know you'd be safe to. But. I just thought. If it were me, and it were you. How I would feel."
"How long have you known?"
"A while" Tim scratched the back of his neck "Your accent is actually pretty unique, and once I caught that, you and Phantom really only differ in your colors."
"The occult books - You were trying to tell me."
"Eh, to let you know I wouldn't mind. Maybe do a bit of research on what sort of thing to expect when my husband is an Eldritch Abomination."
"I mean. Unless me keeping Red a secret from you is a deal-breaker. I was kinda worried it would be, at the start."
"It isn't. Okay, wow. That's. That's a load off. But I think I'm gonna have to lie down for a minute."
"Timberlake if you don't come cuddle me right now you're going to have to look for a new Eldritch Abomination to husband."
And they (un)lived happily ever after.
