I don’t know if it would even make sense on second thought, but I thought you could have (maybe) kept Kylo’s helmet on and his parentage a secret until the scene on the bridge.
You’d be thinking “oh shit, is Han going to try to fight him?” Then all would be revealed with “Take that helmet off” “What do you think you’ll see if I do?” “My son”.
Would have been a much more powerful scene top to bottom.
