Watch it

“Lost” (9 p.m., ABC). In the last episode before the series finale, all the key surviving players finally come together. This episode was previewed last week at UCLA, and I have it from a couple of reliable sources that it’s freakin’ awesome.

“Justified” (10 p.m., FX). Raylan has to play bodyguard for an old judge. But assume it’ll get more interesting than just that.

Record it

“Glee” (9 p.m., Fox). Neil Patrick Harris guest-stars as Will’s old high school rival, and he brings trouble to the glee club.

“Parenthood” (10 p.m., NBC). Julia has another plan to bail out her dad, and Haddie and Amber’s fight over a boy ripples through the whole family.

“V” (10 p.m., ABC). In the season finale, Erica goes on the offensive on the mothership. I’ve heard this series has gotten better in recent episodes, and it’s been picked up for a second season, so maybe it’s worth getting back into.

“Real Sports with Bryant Gumbel” (10 p.m. HBO). Among other segments tonight: An interview with former Raiders head coach Lane Kiffin, who dishes on Al Davis.

Games of the day

Stanley Cup playoffs: Sharks vs. Blackhawks (7 p.m., Versus). The Sharkies lost Game 1, and face a must-win situation tonight in Game 2.

Champions League semifinal: Inter Milan vs. Barcelona (8 p.m., Fox Soccer Channel). The game was played a couple of weeks ago, but a matchup of two of the world’s premier teams will serve as a good warmup for Saturday’s Champions League final, and the upcoming World Cup. If for no other reason, tune in to check out Lionel Messi – he’s worth watching.

Skip it

“The Hills” (10 p.m., MTV). A certain couple finally antagonize their friends and family enough to receive some unwelcome blowback. Wow, what took them so long?
