In episode 23, Angelo and Nicole look at the Star Trek trope of the depressive time-traveller, linking Star Trek: Discovery 2x11, “Perpetual Infinity” with the Star Trek: Voyager season four two-parter “Year of Hell.” Topics include: time travel as academic mastery, the scientific method, Chakotay’s authority issues, Control as messianic proto-Borg, and the evolution of sadboi Tyler.
