There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Keeping the territory or stuff like that doesn't mean, necessarily, that the male defending won, far from it. There are countless examples of the male defending the territory losing the clash but keeping his status.
So that aside, could S8 have won by chasing RR off at the end? Sure, nobody saw it nor is there any evidence pointing out to that not being a possibility. Just as RR could have been the one chasing, or maybe neither submit and they just stopped fighting and walked away, which also happens.
But what we can say for sure is that while they were fighting, RR performed better and inflicted more damage... Much more than he did to Mandevu who was completely hopeless for several minutes, though it seems S8 inflicted some damage back which Mandevu seemingly wasn't able to.
