Right ya git, you'z a Gretchin now, everything hates you, you have the strength, stamina and survivability of a small child and even your boss might use you as extra ammo. The good thing is there's a lot of you, as in, billions.

But are you useful?
"Indeed you are useful, you the only one who can build actually, so make those pile of guns so your boss and other orks can get shit tons of fucking stikkbombs and bomb everyone"
