Text: It comes as quite a shock to watch a warrior performing his final gesture of ritual suicide and realize that it's only a puppet.
Entailment: You are completely fooled into thinking the puppet is a real warrior, and this creates a feeling of shock when you realize it is a puppet.
Contradiction: It is obvious all the way through the dram is being enacted by a puppet, and it is hard to focus on the emotions being portrayed, because of this.
