It did come to a sudden, crashing end with the revelation, but then again, what would Burke accomplish if he pursued making Roger pay for what had happened? Burke was now getting involved with Vicki who was already pretty much a part of the family, he had a fondess for David and what benefit would there be by harming him, and he developed a certain respect for Elizabeth who had suffered enough. Burke was wealthy already, building it up after his release from prison, so an estate and businesses more in his pocket would accomplish nothing in that area since he was richer than the Collinses.
Still, it would've been nice if he would have made Roger pay in some way, such as making him dress up in one of Mrs. Johnson's outfits and forcing him to go to the Blue Whale or the Collinsport Diner and apply for a job just for the enjoyment of the humiliation.
