IVing the IV..."means we been walkin and talkin too long"

[Mark Kohut]

Classic prison movie scene where prisonoers are being watched, maybe overheard, triggered by too much time together. 

Rat here is El Huevencito
soon to be deceased on shank artist's Tariq's block.

just saw Woody (!) Allen's take-off on this in his early movie where talk is cut so short that nobody tells him the break is off......he is schlemiel-befuddled way beyond tough-guy Glen.
