Love does not last forever. People fall apart. Relationships break up. Many knights are burdened with a broken heart, disillusioned with the folly of love. Not all knights survived the Skylark crash. Not all knights return from the Clockworks.
To show the fickle nature of love, I propose that a broken version of the Love Puppy is released, in memorial to all the relationships broken, smashed like a love puppy when a squadron doesn't need its healing properties any more.
This is the best thing ever. Really. It is.
