Question: do hank and wu come back to life?
Answer: At the beginning of the night, Nick (David Giuntoli) realized that both Wu (Reggie Lee) and Hank (Russell Hornsby) had been killed by the Zestörer, and he was goddamn devastated. He tried to use the magical stick to bring Hank back to life, but it was no use. And the casualties didn't stop.
