When Vincent Ingram (Traveler 001) is looking at his son's childhood videos (8m38s), the soundtrack is Wagner's Lohengrin, which is an opera about a wife who died after forcing her husband to reveal his true identity.
The coordinates given to the Travelers, 47°33'17.6"N 122°03'54.7"W, are located in Lake Samammish State Park, just east of Seattle, Washington.
At the end of season 2, "001", Dr. Perrow leaves Vincent Ingram's hostage location via a grand glass-sided staircase into a lush forest, this is the same location, and even a slight copy of a similar scene in Legion, where the psychiatric therapist Melanie Bird, living in her Summerland home with her frozen husband Oliver, similarly descends said staircase.
