Born with the power equivalent to that of ten Harbingers... and yet you've been using your power against the Fatui for your whole life. You started off with killing Tartaglia, and then you made short work of Pantalone. Now, you're looking for the Eighth, Signora.
In truth... she isn't hard to find. She and Venti are... duelling, from what you can see. And then... she suddenly steps back. Your eyes widened in horror. You knew exactly what she was going to do. And, in the blink of an eye, you jumped down, and you grabbed Signora's arm. You spoke.
"Look at me, Rosalyne. If you take Venti's Gnosis, it'll set up the stage for your fate. Your life will end up playing out the exact same way as it did in the other universe, with you being executed at the Raiden Shogun's hands."
