If you've gotten the endings where you fill one of the bars, I think it's either full both. Or don't fill any bars till you've used up all the turns. I'm unsure though because I haven't played in awhile.
I tried both methods and even with both bars more than 75% and still I couldn't get the end
Well... I forgot to edit my previous post but, the way to get the 3rd ending is to fill neither bar, and reach -1 time left.
