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.
You need to keep in mind that much of how it happened is especulation. There is nothing that says they let the 5th brother die out of fear or something like that, I don't think they even knew where their brother was, you can see in the Birmingham males thread how males sometimes separate from each other for long periods of time.
Second of all, I read a report that said that Kinky tail chased them and that they run, but it's clear they separated in said chase and ended up surrounding him. In fact, if you check the video of the fight, you can see one of the Majingilane approaching the place where his brothers were fighting and in the moment the camera gets him he's 50 meters away from them, so possibly he was even farther.
As for Mr.T, maybe he had separated from his brother, moved somewhere else to rest or maybe he chased along with Kinky tail and got lost in the case.
Regardless of how it happened, it all comes down to a lot of especulation and when that happens it may cause we lose sight of what is really important, that is, the amazing sighting of the fight.
