>>103358232not him but tell me anon, Was Mr Greg about the romantic relationship between Greg and Pearl or not?
if the answer is No then the episode was altered and Joe Johnston thought it was important to tell us. The scene for the song It's Over was about Pearl understanding her feelings for Greg and never mentioning Rose.
Joe says it changed because of the time what means it's supposed to be a canon GregPearl episode. We know the song It's Over isn't about them in a romantic relationship so the song can't be sung during the scene Joe described.
The episode is the ending of an arc began in early episodes of the season 1, the ending of the arc couldn't be anything else than Greg and Pearl as a couple. Check Space Race and Reformed. I can talk about it for a long while but the foreshadow was clear in this regard Pearl and Greg had an instantaneous parallel in Greg's uncles who were married and enjoyed to build up planes
The episode Mr Greg itself shows inconsistencies, we can talk about them too
