^You don't have to use spoiler tags for that b/c it was in the promo. Yeah, it looked like the Grounder tosses a knife on the ground and basically tells them that they're going to have to fight to the death.
Since we basically got a similar scenario with Lincoln and that other Grounder in Mount Weather this last episode, I think the outcome will be quite a bit different. Maybe I'm too optimistic but I think both Kane and Jaha will make it out of there alive. Remember there's the search party that Abby sent after Kane so I'm hoping that they make it there on time.
I'm hopeful that before things start getting crazy that we'll at least get a scene or two where Jaha tells Kane about everything that's happened to him since everyone last saw him.
