I realised that I forgot a little piece of Dialogue between the Mayor and Danny, so here it is.
The Mayor glared at Danny through his lidded eyes.
"Somehow, I don't believe you."
"Well, I'm not lying." Danny gave a small shrug at him. "I'm really not planning anything big this working week."
The Mayor stared at Danny and after a while he nodded. apparently satisfied.
"Okay then. Just keep what I said in mind. Your pickup's wellbeing hangs in the balance." Christner reminded. "That was all I wanted to say so you can go now if you want."
"Before, I go. How did you know?" Danny asked.
"Excuse me?"
"All those points you mentioned, the forged documents and conviniently missing files, is just standard procedure for proxy companies. How did you know I was the Techno Commander?"
"Despite the fact that you just confirmed it now?" Christner smiled at Danny's glare. "No, don't worry. I actually figured it out through a very complex system of analys-"
"It was the name wasn't it?"
"In... simplicity, yes." Christner nodded. "While almost everyone is going to look at that ingenoious name and immediately write it off as far too easy and likely unrelated to any Villain activity, attributing the name to some shady CEO or Marketing intern, some of us aren't fooled by even the most effective disguises. Not to mention that you, the Techno Commander, is the only Evil Genius that was left unaccounted for so it was easy to guess your other identity when I confirmed that you were an Evil Genius."
"You said us. Who else found out?"
"A local hero actually." Christer's grin widened in amusement. "He has sent at least a hundred letters to City Hall asking, then demanding and finally begging us to investigate you for being a possible front for a Covert Evil Genius operation because his own superiors thought his ramblings were baseless. Stupid PRT agents. He even had complex flowchart diagrams and everything."
"And you aren't?"
"No, Danny. I'm not going to investigate you. Hopefully, If I leave you alone long enough, the agencies might come back and I'd finally have a good place to put my Niece."
Danny frowned.
"I don't think a spy agency is a good place to raise a kid."
"Oh you haven't met Dinah. She really needs some proper direction in her life. And maybe some self defense courses."
Unwilling to be part of a discussion of whether a ten year old needs to be in boot camp, Danny simply nodded and got up to leave.
"Oh, I almost forgot to ask." Danny paused at the door as he remembered. "Who was the hero that found out."
"Oh. It was Armsmaster." Christner smiled.
