Alfendi needed to be fixed.
This lie of another personality he had was digging far too deep, and not supposed to exist.
Others accepted this lie, this calm side of him that had no reason to be inside him any longer.
Placid was a nuisance, a waste of time and only made his head hurt now. Just not him all together, in every sense of the phrase.
But he was always there and would always be there.
Because Placid was a part of him apparently, and wasn't letting go just yet.
Lucy loved both of them, too, and said that he wouldn't- no, couldn't- be Alfendi without each other, Placid and Potty.
Of course, all Potty could do was sigh, knowing he would never be the same, since it seemed like whatever Lucy wanted, he felt obligated to give.
