Adrift: Part II (2) (S07E01)

Harm's survival in the vast Atlantic depends on Mac's psychic skill, introduced in Season Five's "Psychic Warrior." Meanwhile, Mac is grappling with her mixed feelings for both Harm and Mic. As he nears unconsciousness from extreme hypothermia, Harm fires several warning shots, which successfully summon a rescue helicopter. Once aboard the USS Patrick Henry, Harm's condition deteriorates, but Skates' encouragement helps him rally. At Bethesda Hospital, Renee discovers that Harm has partial amnesia and doesn’t recall their relationship from the past year. Mac’s uncertainty about her upcoming wedding prompts Brumby to return to Australia. When Harm calls Mac to invite her over so she won't feel alone, she arrives only to find Renee there first with the devastating news of her father's death. Left in the rain, Mac finds herself utterly alone.
