Person of Interest, 9 p.m., CBS
What a great season this turned out to be. I love when a new show starts out intriguing and then gets better. Such a rarity. Tonight, in the season finale (it has been renewed), all hell breaks loose as the government closes in on Reese. Finch, Fusco and Carter must save him! Do you think they will? And do you think they will finally explain why HR is called HR?
30 Rock, 8:30 p.m., NBC
In the season finale (renewed!!!) jack asks Liz to officiate at his and Avery’s vow renewal. Remember what happened the last time Liz was at Jack and Avery’s wedding? She ended up married to Jack. So this could be fun.

Hope you didn’t love this, because it ain’t coming back.
