He might be reacting to the episode, he tends to do that sometimes. He seems to have delayed his hints to mondays like he delayed giving spoilers by a day too?
But if hes talking about the chapter instead, that does sound promising potentially!
Maybe an amazing reveal of Elbaf itself for real and thus Yggdrassil and w/e else we're expecting ofc? Giants, giant buildings, giant animals and thus their architecture, scenery and w/e fantastical things Elbaf will have?
