No I think either option 1 or option 4 as is would be the most effective, dialogue-wise.
It keeps it simple, to the point, and easy to follow.
Also might want to consider the KoR calling him Kylo Ren instead of Kylo. This is what everyone else in the films calls him, other than Supreme Leader. Think of it as a name like Obi-wan except Kylo-ren. When they call him Ben it’s mocking him because they are removing Ren, the title of respect and reverting to his real name, Ben.
