Roy was dead by this time.
The twins had demanded Al hand over his fathers shylock book and tools for removing vehicle VIN numbers.
With Freddie Dinome in jail, The only person Al could turn to was Nino. Al asked Nino where his father kept a stash of guns.
In response to this, Nino sent the twins to run Al's car off the road where they gave him a beating.
Given that Richie Dinome was murdered in his home not long after and the disappearance of "Dracula" - I would say that Al was lucky to get off with only a beating!
