This ones written more from Tim's pov. Some knowledge on the New 52 will help explain events and its chronological. I won't actually spoiler any events.
Disclaimer: Ha! If I owned DC it would be chaos.
Characters/Pairing:
Jason/Tim

12:21 a.m.

Sure Tim was an ass to Jason last night. He had a reason. Not a good reason, but a reason. He needed to sort out his "romance issues". Although venting on the person who was the issue wasn't the solution. He was suppose to confess to Jason that he had strong feeling for him. Not show him how much of a dick he could be. Tim was already thinking of a way to apologize, but it wouldn't happen soon. He was returning to his team after a meeting with his "family". the topic of discussion, the Joker. He was back and from the way it seemed he wanted to down the Bats. But that's not really surprising, its the fact that he's personally targeting them.

1:45 a.m.

Great. Tim managed to captured by the Joker. The first time he woke up he was in his original Robin uniform now he's back in his Red Robin uniform, laying next to Jason. How did they both end up captured? "Where are we, baby B?" asked Jason, just now getting up.
"I have no clue. Maybe an abandoned warehouse," said Tim. The events after that were horrible. Joker had them all tricked.

The next day 2:17 p.m.

Everyone was still at the manor. Tim really didn't feel like leaving yet. He has a chance to apologize to Jason. Now was better then never being able to, and they already almost died. What if they're put in that situation again? then Tim may not be able to apologize.

2:45 p.m.

Tim headed down the halls of the manor to the room Jason was in, his old room. He knocked once on the door and Jason quickly got it, "Baby B, what do you want?" asked Jason.
"To apologize for how acted the other night," Tim said, he was still thinking about what he should say.
"It's okay, Tim. I guess it's normal for someone to be pissed when they fall in love. Sometimes I get pissed about it too."
"But I was going about it wrong. I didn't confront the issue about it, I vented on the issue."
"Wait, what?" asked Jason with the puzzlement written on his face. Tim sighed, did he really have to explain this?
"You're the issue. you're the reason I'm in love."
"So Baby B has a crush on me," teased Jason and he successfully made Tim blush.
"Yes, and I don't even know how the feelings appeared."
"Look, Tim if you're afraid that i don't return the feeling you're wrong," Jason's tone changed to a more playful manner.
"So you-?" Jason cut him off by pressing their lips together.
"The feelings mutual," said Jason when he removed his lips.
"Guys, keep it PG, Damian still lives here," said a passing by Dick. Great, that made Tim blush even more and made Jason laugh.
"So, when we're not saving people we go on dates," said Jason who was looking directly into Tim's eyes.
"Yeah, of course," said Tim with a smile. He already loves this relationship.

I'll take requests for the next part.
