Hey Lags, i found the Mariko quest, is it possible to go back so i can see both outcomes? (quest completed, and failed)
Well done, I honestly didn't expected anyone to actually get her quest.
No, You have to erase 'All Memories' which basically resets game to starting point but with most items intact. If you do choose to help her there is a way to get her those remaining animations but you have unlock some other animation first. Since you will be changing the past some events no longer happens.
