Obviously here to congratulate yah and what not for 2nd place, so blep :p.

However, let's get to the content of echoes and giantess. From echoes I love how the title just reverberates in unidentified person's (UP, which is ironic that they are identified as that) life, but with her vestige. It mattered not that we know gal-friend, who she was or the actual significance, the knot is clearly banging us over the head. (To be clear, mój Ukochany does a great job at making sure we know this all but I'm on a different hunt here.) And the connection is still tied, whether or not she is truly dead to UP or not - just another memory that haunts UP. And while it is easy to say UP suffers from delusions, that In-Itself is a delusion to think UP suffers and has no reason to see her.

The Giantess serves as that look back to the times of classical vs Neolithic a la complex tribes. Of a World unbecoming as another becomes, where the old societies are overthrown and lost to the wayside (like the ancient societies a la Sumer or Hindus River Valley) and new ones take their stead. Where we potentially forever lose the connections to old societies as they die their third death (first, physical; second, family; third, legacy), yet the Earth grows over them and absorbs them back to the Earth of which they have borrowed oh so long ago. To be lost and then buried on top by the civilizations that once sought to destroy them when they face their eventual deaths for new ones to overtake them. In that sense, the third death is null yet affirmed; to be not lost but yet never to be comprehended last by a careful eye mucking about. And yet, despite everything, they are still there even when they are gone as the new civilizations and the Earth has consumed the Giant civilizations all the same; forever lost in the thoughts of both and granting the foundations of the new; to reshape and make leaps to new endeavors possible as we lose the ability to see the hardships it took to get there.

Indeed an echo self-lost but finding home in everything it wished it could've been in.
