@ Androyd09 don't forget, the Sisters are immune to pain now. The Splicers also evolve too, in one way or another, but you're right there. Alpha series were scrapped mainly because of the bond, not the armour. @ Anon the Tin Daddies are conditioned to keep their Sisters safe, even going as far as dying, although Alexander may not have intended them to die (Suchong was dead at this point). And it does make sense that shooting an explosive would detonate it. And to avoid confusion, Suchong died before the Alpha series were "perfected".
