Neither duck can understand how the other is so happy with the fate they initially didn't want.

Okay, so lore drop about my Ducktales & Darkwingduck sonas who also happen to be AU's of the same guy lol.

Alador [Left] Is the AU of Ambrosia
In this universe none of the bad things happen to him, he's raised by his parents and gets to be the good guy Agent he always wanted to be. However, but the time he hit his early 30's he was burnt out and bored with life, until he got to go undercover with the villains. Here he found his people, fell in love and betrayed SHUSH and joined the villains.
[i.e gets a mind-life crisis and then gets to be as camp as he wants with 5 boyfriends /lh]

Ambrosia [right]
Was kidnapped as a young child, and FOWL tried to turn him into a villain and join there side but he never caves. After he's mutated he eventually manages to escape, but his parents turn him away refusing to believe that it's their son. So he has to turn to petty crime to surive.
Until eventually he meets this worlds Darkwing and it goes from friendship, to trust to love. He gets to be the hero he wants, even if he's still a little morally chaotic.

So while it seemed like at first, they both wanted the same thing, it ends up changing, and Alador would be fiercely jealous Ambrosia could become a powerful villain with little effort. Whereas, Ambrosia still wishes SHUSH would actually trust him.
