True, but in this case, he'd already ordered Mary to kill him. He could've stepped in, ended it all in a few gunshots, then let Mary take all the credit. She thought killing was fun, she wouldn't mind the blame going to her. It is speculation to say TCM explicitly betrayed her, but there is evidence to suggest it. This is the man who had his family murdered once they got in the way of his ambitions. Now that everyone knew Fabletown's resident mirror-walking psychopath was his strongest assistant, he couldn't keep up the ruse of him being a friendly, compassionate man without getting rid of liabilities. Mary became a liability, just as his family did, and he had them taken care of. Yeah, running would've caused her problems, but that still sounds more appealing than letting yourself get killed by an enemy you know you can't defeat. And TCM could've easily shot Bigby in the office, but he didn't. Why? I think it's because he wanted a fair trial. He wanted to be able to convince everyone he was right. TCM's very charismatic. He knew he couldn't win in a fight, but he could win with words.
