Does every single cartoons relationships and storyline always happen somewhat around the same time I'm not comparing adventure time to any other shows I'm just saying similar things are happening to one another I mean when frost and fire aired a similar episode on another show I can't mention was announced about two weeks after and then too old aired on the same day and same time as that then came the same shows next episode as a follow on along with earth and water

Then on the same two shows on adventure time the red throne aired and then another episode focusing on love life aired and not to mention breezy aired along with another romantic episode too from the other show

Can anybody find out why this strange coincidence is happening and why the subjects on both shows are mirrored at the same time
