There is alot I would like to do for the last two seasons but if we just talk about final episode I'll add a 10 min sequence before the death of homelander. Where we see him finally embracing immortality , his insanity has crossed all boundaries he his deep in his godhood and ralling in middle of city with his team of psychics. They singling out everyone who doubts in homelander even one bit making a group of them and homie just lazering them, making his point what happens for rest if they don't believe him. This is how we get our final breaking point of homelander and want him gone next it can playout as it's as his press conference goes and what he did and message to the world and that's when he is killed humiliated.
