Jason wasn't much of a pop fan it was so boring, kind of music Dick preferred, but not him. Rock was his preference. He has a couple of favorite bands, but his favorite is that you're a singer with a strong voice, and there's nothing sacred about Jason if he even has a couple of posters of that band in his apartment.
On his birthday, Jason thought everyone had forgotten about him, but Tim and Dick, knowing about his hobbies, gave him a ticket to a concert. It even warmed his heart for a while. He spent whole time at concert like a child watching bright fireworks, and when Jason found out that you were signing autographs, he went there first, pushing several people because he has the right. Let them wait.
— "Hey. Can you sign my notebook?"
Jason said when he managed to get closer, the whole group was already on vacation and you, being the lead singer, agreed to give a couple of autographs and he even felt joy.
