Lights (SPOILERS!!!!!)
It just struck me...
the guy in the cellar, the original one.
He was sending Morse Code messages via the lights because of his RESPECT for Park (home owner).
Surely HAD anyone deciphered the messages (and it seems the kid did but the film doesnt use that discovery at all - as mentioned in another thread) it would have given his game away and his hiding place would have been reveealed and he would have been found, thrown out, found by the loan sharks etc? So why would he risk his future by signalling that he was down there?
Secondary to that, are we also to beleive that loan sharks are noble enough to not come after family members of a debtor that disspears ? [ This comes under suspension of belief for film/theratre so isnt a biggy. Just seems soewhat "decent" and "noble" !! ]
I fully accept I may have missed some nuance :-)
