This week, Tendi and T’Lyn learn the usual Star Trek lesson about co-operation and competition, Boimler and Rutherford learn that Starfleet uniforms are less absorbent than is sometimes necessary, and Mariner learns that the real Inner Light experience comes from the friends (and murderers) we meet along the way. And Data shows up too, is just as delightful and wise as we always expect him to be.
