Episode´s moral, meaning of Pharynx´s transformation. Anon 11/27/2020 (Fri) 18:13:58 No.6939 del
The main moral of the episode isn´t thrown at the end but in the conversation that both Trixie and Dolores have with Pharynx around the 7th and 8th minute. Both unicorns explain their own pasts in order to convince Pharynx but they don´t apparently get any outcome by explaining them. This message is also complemented around the 12th minute, when Pharynx is disguised as a rock, listening to the whole conversation that Trixie and Dolores had about him being a lost cause. There is a key line that Dolores says about Thorax: he doesn´t only have to deal with his brother but with his duties as a leader as well.

This means that Thorax has actually found his role and he has managed to figure out how to act diplomatically and make significant reforms with his people (while receiving huge complaints from the rest of the changelings for disrupting them in their business). In his defence, Thorax tries to put a vote of trust towards his brother, hoping that eventually, Pharynx makes things easier for him in order to establish properly all the changes and work out nicely. However, Pharynx hasn´t found his role because he misses the old days as the head patrol, with his conviction that there will be enemies coming up to the hive (he is true about the fierce Maulwurf though)

Now, there might be a belief that Pharynx transforming into the new design means that he has lost his edge and charismatic attitude (which works pretty nicely in this episode. There are some huge slaps thrown from his mouth to the rest that deliver a chuckle and his attitude is hard not to fall in love with, the contrast between the good vibes from the rest of the cast and his actual way of thinking without caring what the others think about him (in short: he is based) causes a very funny experience at how he breaks the schemes out of everyone).

Let me say that Pharynx´s transformation with the butterfly wings doesn´t represent a twist in terms of reforming him with a 180 in his mind but more as a sign for telling that he has managed to find his purpose within the hive. As much as you have to agree with his points that he brings up in the Feelings Forum or with Trixie and Dolores, he forgets about the little detail that his purpose doesn´t consist in conquering the rest of Equestria but with the defence of his species.

His actual role changes from thinking that he is the head of a patrol to turning into the Minister of Defence for the entire hive.

Thorax, while displaying his best with his role as a leader and diplomat (proven in School Daze by the way, he is very peaceful for real), he does display flaws in his way of approaching the military field in which he doesn´t shine all that well. However, his flaw has proven to be characteristic from him since his childhood while Pharynx has always shown more passion towards the matter.

The transformation means that he actually manages to complement his brother and finds a role within the hive. He isn´t hated among the other changelings because of his way of thinking (in fact, he was given the time to speak in his own defence in the Forum in public), he is despised because his approach doesn´t fit with the current circumstances. It´s not about the way that he acts but the way in which he applies his views in practice. In this episode, he has been through a way to reconsider his own place. Even though he has been in the verge of being kicked and the others have tried to convince him constantly, his purpose has been found because of his own reflections.
