Dick didn't know how to fix this. Because all this happened because of him, as you, his sibling, asked him to help you and the Titans on a mission as you had a bad feeling, and he declined, not because he was busy, not, he wasn't, it was because be was feeling petty and arguing with Bruce, and leaving for a mission meant 'losing', that argument.

You and the Titans were on that mission a few days, then weeks, then months, completely MIA, and Dick felt sick, you had a bad feeling about the mission, and he let you go without him because he was what? Fight with Bruce? Dick fully thinks his actions are pathetic.

Dick now stands outside your room at the tower you're in, as you guys were found. By Jason. Not Dick, Jason and the Outlaws.

"... Baby bat? May I come in?"

Dick eventually forced out. He wants to cry, puke, maybe both, you all looked so... Broken when Jason and his team brought you back.
