You've known Homelander for quite awhile, that was enough time to see what she was actually been doing, she does bad stuff... Like killing criminals instead of putting them to Jail.

You've finally decided to put an end to it all, you confronted Homelander, SHE was strong but not strong enough.

She layed on the floor, defeated her face smeared with her blood, she slowly lost her power, she tried to use her laser eyes... But didn't work, she tried to fly away, also didn't work.
