I hope they don't keep Subaru amnesiac for long.
This is actually pretty interesting and ties back to Subaru and Julius conversation at the beginning of the arc where Julius asks:
"Is it worse to forget or be forgotten?"
Subaru brushed it off with some dialogue but funnily enough now we have Julius, who has been forgotten by everyone, and Subaru, who forgot everyone.
It's nice to how this development ties back to that conversation and I hope It's executed well.
Seeing everyone's reaction should be gold with this discrepancy of memories
And finally, the only person who remembered Julius, forgot about Julius lol which is pretty funny in its own way but mostly tragic to him.
