#4 A Draw

The most logical way for the WWE to end this match is to have a double knockout. The original plan was clearly for the two men to meet in one final encounter later down the line, and presuming that is still the plan, then a draw on Saturday would make the most sense.
There is no coincidence that the company have selected a stipulation that allows for such an outcome, and the fact that it will also allow each man to beat the other to within an inch of their life only adds to the drama.

While the last man standing match is often reversed for an end of a feud, the WWE can still use several other match-types, hell in a cell or ironman, for example, to finally draw a line under what has easily been the best feud of 2018 later down the line.
