Celestia should be happy. She should be able to relax. She should just be able to look at her sister and see her sister. But she can't. A thousand years of fighting off evil has changed her, so while she may have once been able to welcome Luna with open arms, now she must act. She must keep Equestria safe.

She only hopes Luna understands so it won't hurt as much.

Warning: Contains Forced Transformation, Brain Washing, And Badish Ending.
