The Walking Dead
AMC, 9:00 pm ET
No one can say that Season 6 of this red-hot cable series has skimped on surprises -- at least one of them decidedly unwelcome to fans -- so far, and the midseason finale, "Start to Finish," probably has a couple up its sleeve as well. Fans have learned by now never to be lulled into a false sense of security by relatively calm moments, such as the ones recent episodes have delivered, and sure enough, trouble finds its way into Alexandria yet again tonight. This time, however, the outcome may be dire. New episodes return in February 2016.
Holiday Celebrations on Ice
ABC, 3:00 pm ET
The popular group Train supplies some of the music in an on-site performance, but the emphasis is on many of the top names in figure skating in this new special. Kristi Yamaguchi and Michael Weiss are the hosts, introducing Meryl Davis and Charlie White -- like Yamaguchi, also veterans of "Dancing With the Stars" -- as well as Brian Boitano, Todd Eldredge, Kimmie Meissner, Surya Bonaly, Alissa Czisny, Ryan Bradley, and Caydee Denney and John Coughlin.
FOX, 7:00 pm ET
The usually comedic Seth MacFarlane ("Family Guy," "Ted") surprised many people with his producing involvement in "Cosmos: A Spacetime Odyssey," and he may do so again by serving as host of this ceremony that honors scientists and mathematicians. Staged earlier in the month in California's Silicon Valley, the event logically features stars of the comedy series "Silicon Valley" as presenters, along with Oscar winners Hilary Swank and Russell Crowe.
