As Pete posted, I think it's a reasonable inference that he could open the drapes for him.
True Turnbull That's where my thoughts been taking me, too.
No doubt Fredo was guilty of something that enabled the Tahoe shooting
Can't see him killing the shooters so the "little help" I too reckon was opening the drapes
We also can't overlook his many lies
It seems to me Fredo's "little help" was opening the drapes which is the only viable help that I can see Fredo [needed to] pulling off that is useful.... not different to Turnbull's [previous] train of thought
Extract: no one has any other viable "little help" Fredo [needed to] pulling off
Have we ever come up with any other viable "little help" that is useful that is other than opening the drapes?
