                        So Alicia and Cary (Julianna Margulies, Matt Czuchry) are partners now – not romantically, but as two of the newest promoted members at their law firm. Tonight, in a mock trial, the two newbies face off against the old guard, Will and Diane (Josh Charles, Christine Baranski). It’s a fake duel that may have actual consequences, and may have viewers talking. At least it has Alicia talking – to herself. And she’s not happy.

                        SEASON FINALE: Even when the Abbey folks, high-born and low, attend a fair, things aren’t completely without drama. And that goes for this Season 3 finale as well, which aired in the United Kingdom as a Christmas special – but delivered more than a feel-good romp for the occasion.  Check local listings.

                        Last week, The Walking Dead returned with a vengeance – and with an episode that weeded the number of Rick’s team even more, while setting even more powerful forces against them. It may have happened slowly, but it’s definitely happened: By now, our hardy band of survivors has less to fear from the roving packs of flesh-eating zombies than from the bloodthirsty humans determined to protect and expand their own turf.

                        Last week, 
Girls took a one-person detour that took Hannah (Lena Dunham) down a rabbit hole of unexpected and confined drama, much like the classic 
Six Feet Under episode that focused entirely, and surprisingly, on Michael C. Hall’s David Fisher, as he was abducted by a young sociopath. (For a full review of last week’s 
Girls, see Eric Gould’s 
Cold Light Reader.) This week, 
Girls returns to its usual multi-plot structure, but still has its surprises – especially in its lengthy pairing of oil-and-water hot-headed guys Adam (Adam Driver) and Ray (Alex Karpovsky).

                        SEASON FINALE: This clever stop-animation show always is worth a look – but especially so in this new season finale, during which, in one sketch, it transforms Joss Whedon – creator of Buffy the Vampire Slayer, Angel, Firefly and Dollhouse – into a vengeful zombie set on cutting short people’s lives the way the networks have cut short the lives of his various series.
