I just finished Priority: Rannoch.
I chose to let the Geth upload the Reaper code, and the Quarians got wiped out. I was unable to get the Quarians and the Geth to make peace. At the end, Tali jumped off a cliff, and there was a Paragon Interrupt as Shepard walked toward Tali. It looked like Shepard was too far away to save Tali. I had set down the controller and couldn't activate the Interrupt in time.
What would that Paragon Interrupt have done?
