Aaravos will come out in Season 6 and he will be a big boy - Theory
So I just finished watching Reel James' interview with Aaron Ehasz and there was an interesting part regarding Aaravos (38:30). So Ehasz mentioned how a part of the finale was overlooked by the fandom. I personally noticed it on my first watch but I didn't know what to think of it. Here is the shot he was talking about:
James' theory is that this skeleton is some kind of sea creature that has to do with "swallowing" and to that, Ehasz says he is on the right track. If you go back to the episode however, 2 minutes after this skeleton is shown, we get Aaravos saying this:
Well with this information I came to the conclusion that this is Aaravos' skeleton! Hear me out.
First of all the pearl is positioned on where the heart/chest should be. Is it a little hard to tell so it is either the heart or the star that we see missing on his chest:
Then again, we have the intros:
Being a Star-touched elf, it would make sense for him to be of this size, which would also allow him to "swallow" people (I am holding myself from making Virravos jokes *hem *hem). That makes him a literal dark hole doesn't it?
Oh and by the way, Ehasz says we will find out about the skeleton next season so if my theory is right, Aaravos is coming out in Season 6. I mean he better... we only got 2 seasons left!
P.S. It is the second time Ehasz makes a joke about the gang playing bowling with the pearl in the beginning of Season 6 (Twitter + Interview). He likes that joke too much for it to be far from reality.
Get ready for our big boy to come out soon!
