Spoiler for theories and next episode:

I believe Seiya is trapped in the core of Mars, and the little pieces of Aria's trident that fell in that crater will be what helps him release himself, or awaken him. I am still kind of annoyed at the previous magazine spoilers since they made it sound like Yuna was going to save the day next episode, but the more recent description for next episode says she gets beat up and is unable to do anything too, and that's when "The Legendary Hero" shows up.
I am excited to see Seiya though!
