also for that matter, considering that goro knew sumire through her father at the TV station, does that mean that goro always knew that she was sumire............

sumire: my name is kasumi
goro: ????
sumire: my sister sumire died last year
goro: ????????
joker: sorry to hear about your sister, kasumi
goro: ???????????????????????????

sumire: i need to find out the secret of why this palace showed me that terrible video of sumire's funeral!!!
goro:

this screenshot is goro code for "joker how the FUCK did you miss the fact that this girl is literally an entirely different person than you think she is"

goro watching sumire desperately trying to uncover the truth of her own identity while knowing full well exactly who she is: this is kind of fucked up but it costs zero dollars to stay in my lane

im getting way too much mileage out of this considering that im not sure if it's ever actually confirmed that he knew from the start
