yeah this lantern rite confirmed me
furina was not about "sorry i faked being an archon", she was "sorry i was a powerless archon"
she doesn't deny herself being an archon to fontaine, neither is everyone else.
i was waiting for lantern rite to see how her convo with zhongli
although this doesn't reflect anything, her dialogue from previous event, her sq, & her stance of her circumstances in this event
at this point, it's only fandom who is being fixated on whether furina was(is) an archon or not
