I think the Halloween Special’s characterization is canon, even if the plot line is not. And this is important for the character of Dolphin.
(Analysis below)
I know that a lot of people are eager and happy to consider pcfc’s Halloween special—Revealing the Trout-pocalyse—not canon both because a lot of the main cast was put into the background and a whole slew of the throwaway background characters became the main cast with some notable exceptions
(like, God [Mary] and Yuri God [Niki] were present but not a lot was seen from the mainstays like Elo, Skew, Bridge, and Ethan and so on so forth)
And because of the whole “everyone died in the end” nihilistic-type ending that makes the practically-movie-length-special a ‘pointless waste of time’
But I think this was the writers’ way of trying to softly test out how audiences would react to an expansion of the cast (the fandom reacted poorly) but this means that the characterizations in the Halloween special may very well be canon. Which means… I don’t want to see any Dolphin apologists!!
(That is a joke, the type of dolphin apologists i don’t want to see are the people going “she never did anything wrong and it was the writers who maimed her character”, and to them i say… you wouldn’t have been shocked by the ‘Steals Skew’s Godhood’ arc if you cared to watch the special.
She can do catastrophic damage and do it for fun just as much as Skew and Mary often do in every episode and I’d like to see some critical thinking about her actions from before that pivotal arc. Everyone talks about how the fandom mischaracterizes Bridge, but no one is talking about how infantilized and sanitized the fandom made the ‘God of Mercy’.)
The Trout-pocalyse was foreshadowing for Dolphin’s character, and the fandom just wasn’t paying attention.
