Re: SUPER UBER SPOILERMANIA: The Ending... What Does It Mean?
I do think between the time the final battle in Greenwich and Thor's conversation with Odin/Loki some time has passed. The thrown room has been completely restored so there has been some time for something to happen with Odin. Of which the mystery is a great, very well scripted IMO.
In Earth's Mightiest Hereos season 1 the whole story was brought together at the end by Loki who had manipulated countless people and battles in order to keep everyone distracted why he managed to corrupt Yggdrasil which gave him control of the Odinforce and allowed him to capture and imprison Odin and take the throne, only for a final confrontation in Asgard between himself and the Avengers.
