I don't want to say that episode was tense, but if my phone had rang my upstairs neighbor would have seen something like this...
dynamics of the Royal Guard. Of Menthuthuyoupi we've seen nothing to indicate that he's more than what he seems - a straight-up muscle guy who doesn't overthink what he's ordered to do. Shaiapouf is the strategist of the bunch, though so emotionally volatile that it makes him unpredictable. It's obviously Neferpitou that's the most dangerous, we can all see that - but it strikes me that what makes him dangerous to the Hunters can also make him dangerous to The King.
redeem Killua's trust in him; Meleoron focuses on the practicalities of the task at hand and his role in it. Morel - now the undisputed leader of this group - reveals a little vulnerability (he assesses his strength at "35%") beneath his rock-hard exterior, and an expectation this his role as the strongest and most visible is going to be to sacrifice himself. And Knov - his hair turned white by the ordeal he's endured - is tortured by self-loathing over being unable to do more to help the others because his fear is even stronger than his disgust with himself.
saw in Killua that made him think the boy might "fade away"? It's Killua who's taken on the role of strategist, using his experience as an assassin and the insider info from Ikalgo and Colt (who appears to be watching over The King's diminutive twin) to try and plan for the unexpected scenarios he knows are coming.
"like lemmings" in Knov's words) towards doom and the greatest clash of titanic power in a series full of such clashes approaches, the fate of the story may in fact hinge on how The King answers those questions.
