I also can't figure out the alarm thing: why would it matter? There's three factions of people running everywhere shooting at each other, I don't think anybody would hear it, and if so, I don't think anybody would care. I can't really see what's the matter with Burt: he's locked up, if I were Scratch I would be out to chase those who aren't. Then, after I have things secured, I'd come back.
Also, I don't think Saul will do anything to Scratch: he's in bad shape and the girl is essentially immortal.
