What's Nob Hill and why was Megan sleeping there?

Also if that's supposed to be Titans Tower I really have to ask at this point what sort of security system exists if a guy can climb up a wall (with apparently no special tools) and just pop in through the window.

Now while it's silly I really don't mind seeing her in this. I've wanted for a while to see what Miss Martian would think about J'onn particularly about his death.

And seeing her cry for justice wouldn't be all that bad compared to the others, for one thing she wouldn't be as bloodthirsty as the Hal league has been.
