Saved from the Queen by the Princess

Inspired by the KAEX Challenge: 'Allura Saves Keith' Challenge was before I joined, but this is part of my completing a lot of past challenges. What happens when the beautiful Queen Merla kidnaps Keith... and her reasons have nothing to do with battle... How will Allura handle this challenge? DotU [Keith/Allura] Merla & Lance also major characters. M Rating, but NOT citrus.
