User blog comment:H-Man Havoc/New Squadmate Species for ME3?/@comment-26766637-20110101075254/@comment-217683-20110101202711

How does one "tame" a sentient being? They aren't animals, capable of being domesticated. The only way to control a yahg is to first establish dominance over it. I'm inclined to agree that, due to their backwardness, their status as even bigger galactic pariahs than the batarians, and the general untrustworthiness and uncontrollability of the yahg, they are unlikely to appear as squad members, nor would I want one.

Comparing the geth (who have not, btw, been banned from Council contact - they simply don't contact the Council or any of its races by choice) to the yahg is a pretty specious comparison. The self-imposed isolation of the geth and the forced isolation of the yahg are two completely different situations.
