A surprisingly affecting Kardashian special. Spotlight-friendly sisters Kim, Khloe and Kourtney take a backseat in this hour as half sister Kendall Jenner preps for a milestone birthday (and stakes a claim for her own reality fame). Kendall's ingratiating difference: She's low-key and sensitive. When mom Kris pushes for a blowout in the Bahamas, the teen insists on something quieter, out of respect for "the less fortunate." Impressive! (E!, 9 p.m.)
