If regeneration could really clean their flesh under even their armour, why couldn't it clean their teeth?
Was the skin condition because of the armour that was never taken off or was the skin condition a method of making the infection and gangrene from the armour tolerable?
Or was every drone pulled apart, cleaned, and put back together again like the queen was in first contact?
