Line 58 works as expected.
Code:

c.label:SetHorizontalAlignment( CENTER )
c.label:SetVerticalAlignment( CENTER )
c.label:SetText ( c.label:GetAlpha() )
return c, c.label
end
function KillingBlow:labelScope()
print(c.label:GetAlpha())
end

print("KillingBlow Loaded")
end

function KillingBlow:InitializeEventManagement()
--event registering
em:RegisterForEvent(self.addonName.."_OnAddOnLoaded", EVENT_ADD_ON_LOADED, function(...) self:OnAddOnLoaded(...) end)
em:RegisterForEvent(self.addonName.."_OnPlayerActivated", EVENT_PLAYER_ACTIVATED, function(...) self:OnPlayerActivated(...) end)
em:RegisterForEvent(self.addonName.."_labelScope", EVENT_MOUNTED_STATE_CHANGED, function(...) self:labelScope(...) end)
end

-- CALL

KillingBlow:New()

Table (or top level window) "c" is defined as local in function KillingBlow:CreateControl(), it is not visible outside of the function. However when you have initialized object, reference to this table was stored in self.control, so you can use this reference instead of "c":
Lua Code:
function KillingBlow:labelScope() print(self.control.label:GetAlpha()) end
