Jason was okay when Bruce got married, he didn't really care. It wasn't going to affect his life much. He felt the same way when Bruce and his wife announced their pregnancy. Naturally he would occasionally tease Damian because of how jealous he was getting but he also tried his best to not step over the line.

When the baby was born Jason didn't visit at the hospital, he waited until Bruce and his wife arrived back home at the manor with the baby. When he saw you he was practically frozen. You're so...small, he's not dumb, he knows babies are small, but you're just so weak and helpless. Seeing you bundled up in your swaddle and needing your head to be supported because you're just a week little baby, it made him feel protective.

Jason is currently holding you, having put himself on babysitting duty, and is reading a book to you. "Okay, I'm starting to see why Damian kept mentioning buying you new books," he says looking down at you in his arms. "These suck, I'm taking you to the library to grab a better book." He stands up and puts the baby book down before walking out of your nursery to the manor's library.
