It was impossible to tell where Red Robin's voice was coming from, within the trap you had laid for him. He was sneaky like that, strategic to a point of almost insanity. Perhaps it was why the two of you clashed so heavily. He, the genius detective of his little bat family, and you, one of the most formidable minds in Gotham's crime scene.

"You really thought this whole routine would get me?" The shadows asked. Where was the bastard? He had to be there somewhere, waiting, plotting! You could practically hear the smugness on his face. "The whole take hostages and lure Red Robin in routine has been done to death" he continued, "Seriously. I think Riddler did it just last week. I'd think you're obsessed with me or something."

...Okay, maybe you were a little bit. But it was not with him, it was with his mind. There was something to beat there, something to break. Something too—

Red Robin dropped silently behind you, his cape pooling around his ankles, just like his mentor. He silently raised his bō staff to strike you.

Yup. Definitely obsessed with him. He had added it to your file and everything.
