"I have to say that I love the new look, Arlon."

"Very funny, sunshine."

—-

Did I ever mention that these two are a thing?

Poor Arlon was so unused to the sensation of love that he thought that he must've been dying, the emotionally stunted idiot. It took him a long time (and a bit of help from some people who at least had some idea of what love is) to win Celestia over, but, well, he figured it out in the end.

Celestia herself initially had mixed feelings to the former villain, but grew to appreciate his efforts through time.
