With only 4 unaired-in-Australia episodes to go you might be wondering "man, when are they going to get to Asgard to kick Surtur's ass"?
The answer is they won't.
An ongoing sub-plot in the first half of the season was based on Walt Simonson's classic Surtur story from Thor and we were introduced to Beta Ray Bill and saw the Enchantress become Surtur's thrall. Thor was sidelined at the start of the season to build up this plot and whole episodes were spent setting us up for a big almighty showdown with Surtur presumably to happen later in the season. But the twist is we won't ever see this showdown. The plots for the final episodes do not involve Surtur or Asgard. In fact, they're taking us to Hala for a showdown with the Kree and Galactus. The unresolved Surtur story is obviously a victim of Loeb's insane "it all must be stand-alone episodes" wish despite him hypocritically having been behind a 3-part winter soldier/rulk saga and the upcoming kree story also being a 3-parter. Toppled with the cancellation of the show this only means that we will never have this story ever resolved despite all the heavy set up.
