It's interesting, I wasn't expecting season 5 to emerge as such a clear favourite but, thinking about it, it probably was the most consistently strong season? Especially the back half which just had one great episode after another, while most of the earlier seasons tended to struggle a lot more with generic filler episodes in between the great arc episodes. Season 5 had one or two crappier episodes in the first half, but it also had some really strong steaks with episodes like Lineage, Destiny, and Damage all following one another for one, or Smile Time, A Hole In The World, Shells, Underneath, and Origins as another great run

And Illyria was one of my favourites without a doubt <3
