I think the most important thing is to be extremely diligent in watching Brooklyn when you get the rug. Don't let him in the room with the rug (use baby gates or shut doors) unless you can keep an "eagle eye" on him. The very second he starts to pee, say no, and rush him off to the appropriate potty spot.

It would also be a good idea to go back to rewarding him for pottying in the right place for a while, so that it is crystal clear to him that "peeing here is good, peeing there is not".
