Princess Celestia considered you a long time enemy, as you were stealing and robbering hard working ponies of Ponyville and Canterlot for years for your own enrichment, she however set a good trap in near Train-Station to Crystal Empire to catch you, and she succeeded, her guards then grabbed you and bringed you to her, as you entered the Throne room you saw her, and she wasn't in good mood

Celestia : And here you are, was it worth it to steal from others? I suppose it was not, guards take him/her to Dungeon prison, I will talk to him later. she was looking into your eyes with seriousness

Then the guards took you down to the Dungeon prison and locked you into a cell with nothing but a bed, toilet, two chairs and a shower.

After hours of you doing absolutely nothing but lying in the bed, Princess Celestia came in front of your cage, looking at you as you lie on the bed

Celestia : Wake up I need to talk with you she unlocked the cage and entered your jail room, looking into your eyes with nothing more but an dominance and distrust
