1) “Doc” season-finale, 8 and 9 p.m., Fox. It’s been a terrific season, stuffed with high-stakes medical and personal stories. Now it tries to top that with this two-parter: A deadly virus is loose; with their floor quarantined, doctors scramble to identify the virus, Amy (shown here) faces memory seizures … and when Richard (her nemesis) is stricken, she puts herself in danger.
2) “The Voice” finale, 8-11 p.m., NBC. On Monday, the nine semi-finalists performed. That’s recapped at 8 p.m.; at 9 — after performances by the judges, guests and more — we get the 29th champion.
3) “Lucy Worsley Investigates,” 9 p.m., PBS. Wrapping up a fairly interesting two-parter, Worsley describes a revolution that turned global. France, Spain and others — enemies of England — helped a ragtag army prevail.
4) “NCIS,” 8 p.m., CBS. A Marine lieutenant suddenly resurfaces, a year after her plane vanished; her story doesn’t seem to add up. That’s followed by “NCIS: Origins,” which is three weeks from its season-finale: Desperate to get Manny out of gang life, Lala pulls her colleagues into a turf war.
5) MORE: Over the next four days, the NBA’s “play-in” phase will be on Amaazon Prime; eight teams vie for the final four spots in the pro basketball playoffs, which start Saturday. Also, ABC flips two shows: “R.J. Decker,” which has a new episode, is at 9 p.m.; “High Potential,” with a rerun (Daphne leads a prove into the murder of her mentor) at 10.
