Canonocial order of season 4
 

I’m just wondering what the canonical order of Season 4 is, as Google and Turtlepedia have different running orders

It aired in slightly different order on TV, and "Insane in the Membrane" was originally skipped in its original run. But otherwise the order should be the same as it is in most sites.

Do you mean in which order the episodes take place?

What's different? I know that the Halloween episode was moved to air before Halloween, otherwise it wouldn't have aired until after. Besides for that, Insane in the Membrane didn't air on television during season four. It first premiered on DVD. Are those the only differences?

I remember watching the episodes when they first aired, A Wing and a Prayer aired after The People’s Choice and before Sons of the Silent Age. Also the Halloween one aired at that time of year. I think after The Ancient One first aired, changes may have been made in the episode order. Leo mentioned the Battle Nexus grudge match in A Wing and a Prayer so that had to have happened after Grudge Match. I guess Halloween was moved to be at the proper time of year.

In season 4 stockman's worse than ever, Agent Bishop's schemes are getting better.

Yep. Full chronological order is what I’m looking for

You beat me too it. I was gonna post that myself. I would say that's the definitive episode order for the entire series, but they've got The Christmas Aliens in the middle of season three (rather than at the beginning).

It looks like google has the episodes listed in order of the dates that they aired. Turtlepedia has the episodes listed in the correct chronological order.

One thing is for sure. The early season 4 episodes take place during autumn in New England.

in the uk they put on every episode of season 4 even insane in the membrane.

Nicktoons
 

Nicktoons finally aired it on 2 August 2015.

In the UK insane In the membrane aired on its original run in the uk

I know. In Sweden, the series had already been taken off air right after season 3.
