Could anybody, please, enlighten me as to what "off" means in the following excerpts taken from the script for the TV show "Breaking Bad"? (I've also come across the same use of "off" in other scripts).
"Our two scary Cousins glare at Heisenberg. Off them, wrathful and unblinking, their lips moving in silent prayer... and us thinking ”Oh shit. THIS can’t be good...”
He stands chest-high, frantically splashing water at the last few lumps of cash still BURNING poolside. Off our hero...

Off come their Canali suits.
Off these strange events...
MARIE He must have! Why not just say it?! -- Off Marie, left stewing now
Off Jesse, maybe just now beginning to see the light...
