Around Christmas 2015, John Sharp and his family got involved in the following of Damien Darhk and became test subjects for H.I.V.E., heavily implied to have been drugged into submission with suggestion pills. Team Arrow was later present at Reddington Industrial, where they were being held, but were unable to set the prisoners free from the grasp of H.I.V.E.. When Malcolm Merlyn destroyed the facility, John and his wife, Mary, were among the dead while their daughter, Evelyn, managed to escape. The couple's bodies were recovered from the wreckage on December 27. According to their autopsies, John and Mary died of hypoxia in H.I.V.E.'s gas chambers.
