Already in EA, if you use the tadpole enough times you become a mind-controllable True Soul (The Absolute tries to control you on the bridge, nearly succeeds, and Shadowheart comes along with her d20-shaped Deus Ex Githyan-kina to save the day.)
I got that exact same scene and haven't ever used the tadpole power. I have a feeling it's going to be a fairly railroaded experience with all "choices" leading to one or two outcomes.
