"No plan survives enemy contact."
Luna shuddered. A strange feeling of dread overcame her. "Are you alright sister?" Celestia asked her sister, having noticed her unease. "I'm alright." Luna reassured. "But I've got this feeling that we'vre forgotten something or that we had to do something else." She added.
"Don't worry, if you've forgotten then it wasn't important." Celestia also reassured her sister. "You're probably right."
"Everything is almost ready, it's only a matter of minutes." She casted one last spell into the scissors, which had taken a lot of effort to loosen and cute large holes in the ground and stones. "Lets go over the plan one last time." Everypony nodded. "I'll open the portal/rift with the scissors. Celestia, Starlight and Bagel will maintain it open while I and Luna use the tether to pull Trixie back in equestria. Everypony ready?" Everypony nodded in confirmation.
Luna still had this odd feeling of dread. But she ignored it. It was probably nothing like her sister had said.
