I just watched Hawaii Five-0 7×07 "Ka makuahine a me ke keikikane (Mother and Son)" https://trakt.tv/shows/hawaii-five-0/seasons/7/episodes/7 #trakt
Five-0 must free McGarrett's mother, Doris, when Catherine informs them that she was captured and is about to be executed after attempting to free Wo Fat's imprisoned father. Also, Chin loses his appeal to have Sara's adoption delayed, and she must move to Mexico.
