In November 2019, while working, Roy and Leon entered his workstation. At first, he was merely angered and shouted at them that it was illegal for them to enter, but he soon learned that they were replicants, as they were unaffected by the frozen conditions of his lab. Leon ripped open Chew's jacket, exposing him to the cold and interrogated him while he froze. Roy and Leon found out from him that J.F. Sebastian could get them into Eldon Tyrell's inner sanctum.
Chew lived next to the designer of the replicants' skin, Moraji, and that they would eat dinner every night until Moraji was killed by a bomb planted by Sadik.
