i think one definitely needs to let Kendra take over Manila's body during her date with Jason on the beach to view Kendra's ending
the colored flames represnt justice in blue and corruption in red, their number is tied to each respective value, 1 flame for every 25 points
Kendra's karma depends on Manila's karma , but not sure as i didn't play the corruption route and Kendra in justice route isn't bad.
and i could easily be wrong ^^
