One more foreshadowing from the dream (I was told this by a Japanese friend). In the JPN version of 511, the way Eba says "you" is "chisama" (its an accented variation of "kisama"), which comes from souiCHISAMA! (he never says any form of "you" in the JPN v of this chapter btw)
The Tower scene reminded me of this page https://mangadex.org/chapter/642681/15 I've always loved it for it's Hal foreshadowing but now I realize it's specifically foreshadowing that Baku knows Souichi just lost his memories.
It's pretty depressing that Eko's mom left her, and she ended up disappearing from her son too... (She's a very confusing character, but unlike Eko's mother, I do think Eko had good intentions for Souichi).
Also interesting, but also sad, that Eko and Hal were lonely ):. I guess Tatsuki is like Eko's Baku, hehe. They are even similar personality wise.
Oh and thanks so much for all the detail put into the foreshadowing chart, always appreciate them!!
This series' use of foreshadowing/callbacks is def something I will miss ;_;
