Well, there were/are going to be two fights at least. The second one I planned to have in Wastelands for reasons that will be fairly apparent when we get there and so I don't feel the need to discuss them. I figured one would happen earlier, either at this point or if we did another stop over before the last few worlds or something, a bit iffy on the timing. Either way, I always assumed it would happen because either Thomas or Joshua just got tired of the other and decided to punch it out. But admittedly the reasoning when I originally planned it out was a lot more hazy than now, since it was earlier.
