While Arnox has recently shown his true colors....and proven how naive, socially ignorant, and emotionally spastic he can be....I will at least give him a few points for at least mingling with us. Zok was such an awkward nerd he hardly ever mingled with people outside of his nerd herd, and could have been one of the most boring communicators to ever exist. Arnox at least can discuss some things like a normal person when he isn't fucking up behind the curtain, whereas Zok never fit in with anybody anywhere.
To illustrate, I would say Zok reminds me of a lowly earthworm....that never burrows to the surface even on a rainy day, preferring to hide from the big bad nasty world and stay in his darkened existence where he only feels safe. Whereas Arnox is like a crippled 3-legged field mouse, that chewed off one of his own limbs as his only solution after making a very stupid and obvious mistake while being lured into a mousetrap.... that will probably effect him for life.
