Alex's comments about roaches being gross earn another bit of grumbling in Hajime's monster tongue, mostly just to keep helping to sell his story. Really, he thinks roaches are disgusting too, despite being a rather large sort of one. "I am a highly evolved roach, and as far as I am concerned, I am surrounded by mutant apes. How your ridiculous species is ruling the planet is beyond me."

...yeah, he's going to owe Alex and anyone else within earshot some kind of "I am really not crazy, and I am sorry that I ever made you think otherwise" speech later on.
