How much rage have you little ball of hate.



Kelco had more development in 1 episode than Starco in 4 seasons but in the end he was only a scapegoat just like the blood moon that was reduced to "vendehumo/smoke seller":that something seems important, it has all the arguments and development to be but in the end it turns out to be nothing creating a contradiction (I don't think there is a word for this in english).



It was the little that Cotugno's team did well (Sabrina Cotugno, the one who stole the series from Daron Nefcy in case you didn't know).



And if in a matter of who knew Marco the longest, that was Hekapoo for more than 16 years and that also turns the starco into pedophilia since Marco is an adult man of more than 31 years who likes teenagers of 15 years.



Judging by your comments, you can see that you do not have your own criteria and you reflected in one of the parts of that poorly developed ship (starco) the fact that it is canon does not make it objectively good.
