Saw a clip from 2.5 patch

Dan Heng telling Taoran even after reincarnation he will still be the same person.

The fuck is miHoyo trying to do here?

Are they having trouble keeping their own lore straight or are they ret-conning? Is there some extra context that's missing? (I know that this is on context of the memory potion, which Dan Heng also experienced. But Dan Heng insists he is not the same person while claiming Taoran will remain the same, so which one is it you fucking tsundere? And no, individual variation in response to the treatment isn't enough to explain the difference, because Dan Heng is saying he's speaking from personal experience.)

I agree with the OP, Jing Yuan needs to call Dan Heng on his BS. Are you or are you not the same person?! (But this also feeds into the interpretation that Dan Heng is jealous of Dan Feng when it comes to friendship with Jing Yuan given how insistent he is about keeping the identities separated while also apparently internally accepting he's...the same? I swear miHoyo storytelling drives me up a wall.)
