Maripyaipok's people, the Satere-Mawe, have an adulthood ritual that involves being bitten repeatedly by the most painful insects on Earth for a period of two hours, during which time the person being bitten is not allowed to make a sound or flinch. They've got another that involves the same silence when bitten by a venomous headcrab. Mari has said he'll be first in line to join the Marines if Shephard goes through the ant rite.

This? This is a rehearsal. Fuck it to absolute fucking utter shitfucking hell this is a dress rehearsal.
