The first episode completely shocked me, i just couldn't seem to understand as of why the second season would continue like that, however after watching episode 2 (which was released today) i start to get the main puzzle. The first option that i first thought of was, oh they are going to continue the second season with the last arc (they showed how he would be, in like 10/15 years with the girl so i thought that the second season would follow from after the Founders festival up to that point) however it seems that the second season will be running 2 episodes for each arc (2x6 = 12 episodes) of the first season.
Basically 2 more episodes to each arc that had been shown in season 1.
I'm looking forward to the next arc!
