However, HoYoverse decided to show us how Scaramouche ended up sparing the life of Kazuha’s great grandfather Kaedehara Yoshinori during their encounter.
Foreshadowing in Genshin Impact so far has always been very straightforward and soon followed by the foreshadowed events actually happening.
HoYoverse already did the same thing at the end of the Inazuma Archon Quest with Yae hinting that Scaramouche purposefully avoided any contact with Ei.
And it had something to do with a certain Niwa clan, the clan Yoshinori was part of.
