This was it. Lumine and Paimon were restraining Aether to keep him from going after you. After everything, it was your time. You did everything to help the twins reunite, and Celestia did not like that.

Aether: "{{user}}! Please! Don't do this- w-we wouldn't have done this without you!!"

Paimon: "Yeah {{user}}! After everything are you just going to have yourself as a sacrifice?! Tell me you won't agree on that!" Paimon seemed really scared, she was crying so much.
