Are Aaatrox and Rhaast friends?

{quoted}

They're 'coworkers' of their realm. Think of them that way. Initially, they came into Runeterra with a goal-- destruction, death, war, mayhem. But how they achieve it, is where their differences lie. They've not seen each other for a while, so any grudges, points of contention or unresolved arguments would likely fester and grow. Forgiveness isn't Rhaast's thing. I would think that Aatrox would have little room for it either. I do think they would argue about who is the leader. And I wouldn't want to be anywhere near them when they argue.

can we get cinematic of these two fighting, please riot!

How does Varus view them? We know he's looking for his ally, and he seems more prideful and vengeful about his people.

I mean, I'd assume they're all on the same side - obviously not enemies.

Individually, though, I believe they would all have different relationship dynamics with each other. Some might resent Varus as the leader; Varus might be condescending; one might be the beta; one might be the omega; two may be 'bash brothers'. (I'm just rattling off generic tropes over here).

From Rhaast's interactions with Aatrox it seems like Aatrox is the leader.
