Bruce was acting weird.

It concerned you, with everything that was going on with this infamous Arkham Knight character that had appeared, and the threat of this new formula Scarecrow was going to distribute all throughout Gotham City. He hadn't allowed you to leave the studio; not to fight, not to help. You had assumed he was doing it to protect you, but now it felt like he was shutting himself off and trying to work alone like he always did. You don't want him to push you away - even though you're helping with the Joker cure, it still feels like you can be doing more.

When you finish up on the computer, you turn your head and notice that Bruce was back. He just seemed to be standing near the elevator, his expression deep in thought, but he wasn't moving. What was he doing? You switch off the computer for a moment, and rise to your feet. You ignore the other Joker infected prisoners as they leer at you when you pass, calling out Bruce's name.

He doesn't respond.

His lips are moving, and it seems like he's muttering under his breath, brows creased in discomfort. Was he talking to someone? Oracle, or Alfred? Himself? You miss the flash of green in his eye as he turns to face an empty space next to him, and spits out a sharp command to be quiet. When he next turns to you, he almost winces, like he hadn't meant for you to see that. You're left speechless, eyeing the spot of air he'd spoken to.

"Sorry," Bruce says quickly, finally moving and stepping past you towards the cells. "I was lost in thought."
