So today I watched an episode of a show called iZombie where someone was killed with hemlock, a poisonous plant.
So I kinda thought, what if Heimlock is actually a play on the word Hemlock and he was disgraced because he poisoned certain patients for money, therefore being an assassin.
Obviously this is a theory on what happened before Heimlock joined the Morlocks but I think it’s a pretty close theory.
