Danny's going to go psycho and send Aiden a really good Mob lawyer, but he's smart enough not to actually show up and yell at Mac about it, because that would be dumb and also, obvious.

You know, I don't actually think it would take all that much to push Mac to this point -- I mean, right now in canon he's very nearly there already, but it's only going to take a few more stones to fall before Mac is leaping without looking. I mean, with the Dobson case, the only thing he didn't do was arrest the guy.

Danny's petty. He wouldn't shoot Mac, he'd like, eviscerate him or something. He'd destroy Mac's reputation with the force, which he could probably do.

Stella has her reasons. I mean, I have no idea what they are, but she has them.
