Ah, I remember watching a playthrough of that fight from a YT'er who was being guided while playing Bloodborne
The guy guiding her only told her where she needed to go, etc...
He never told her how to fight or other stuff
He just gave her little helpful nudges so she didn't miss something or get locked out of something, etc...
Anyway, when she finished the second phase of the Friede fight, she relaxed and felt so relieved because it had taken her a LOT of attempts to even reach that point.
She started talking about how she had felt during the fight when the third phase started.
She was so genuinely gobsmacked and shocked that she just watched it happen before she went silent and had a go at the guy for not warning her.
Whereas the guy was laughing his head off cos he was waiting for her reaction to it all.
It was quite entertaining.
