Season 2

@alexeiei Thank you, I was confused.

@alexeiei it's listed here the same way it is on Netflix, with the Christmas Special as episode 1, and the actual season starting on episode 2

@alexeiei actually, Netflix lists the Christmas Special as 2x01. It's correct. Take a look there.

@arthurmeds @kurizh @twistytheclown My bad, you are right. Episode 2x01 was named as a special one in thetvdb for a long time and only now they have changed the name. Sorry.

@alexeiei Officially it's still S02E01, right? That's how it's in Netflix, too. Or am I wrong?

@broodjekipkorn You are right. 2x01 was aired in December 2016 and now the season continues in 2x02. That's how it's in Netflix.
Episode 2x01 was listed as a special one in Thetvdb until now. They changed it.
