"Sorry, it's just uh..." This is really embarrassing for Jason to say, "It's my first date, my first relationship." You don't know, but with the way his life was, he couldn't even think about romance, love and dating. It was all about trying not to die. Again. First, he was busy with surviving on streets, next with being Robin, then being dead and after that Red Hood activities. He can't tell you about his life, though. Jason doesn't want to scare you away.
