I have come across a few phrases while reading a book that either sound weird to me, either seem completely impossible to understand.
I would appreciate if anyone could take the time and effort to clarify these for me (and I can't promise there won't be more, a thick book it is! )

"she never could get it together to visit"
does that mean she couldn't organize everything to visit, or that she was always short of money to do so?

"The baddest apples do full runs"
I had a problem with particularly the baddest word. Is it possible to say that, like in colloquial speech, or (since it was in a dialogue) was it made to look like the person talking was not very clever?

"I wasn't the lit fuse Michael had become"
ok, no idea whatsoever except for maybe that Michael was a bit hot-tempered?

"Make those brisket sandwiches to go"
I assumed he just wants his food out, but it sounded weird to me.

Thanks
