“Revolution” (Wednesday, 8 p.m., NBC)
Now that all of the main adult characters have improbably escaped death — Rachel (Elizabeth Mitchell) survived an ugly arrow wound last season, Aaron (Zak Orth) died for a few minutes ’round the campfire, and now Miles (Billy Burke) conveniently cheated death — can this show stop thinking we’re gullible enough to believe they’d kill off a main character? On the plus side, they’ve ended the lame first-season war with Georgia by nuking it, and this week they’re joined by “Deadwood” alum Jim Beaver, who plays a former Texas Ranger from Miles’ past.
“Castle” (Monday, 10 p.m., ABC)
The spy show equivalent of this cop show used to be “Chuck” — neither show has ever taken itself too seriously. So it seems fitting that one of the geeky action series’ former stars, Joshua Gomez, who played Chuck’s pal Morgan, would end up as a suspect in one of Castle’s (Nathan Fillion) cases. Gomez is as much of science fiction nerd as he was on his previous series, this time claiming he has traveled back in time to stop the apocalypse. Either that, or he’s a killer.
“Covert Affairs” (Thursday, 10 p.m., USA)
Still kicking in the back half of the fourth season is baddie Henry Wilcox, who is played by perennial meanie Gregory Itzen. You’d remember him as the scariest president ever, Charles Logan from “24.” Agent Annie (Piper Perabo) will face off against him, although it’s hard to imagine that doe-eyed cutie being able to take down the cold-as-ice assassination plotter.
“Law & Order: SVU” (Wednesday, 9 p.m., NBC)
Now that conspiracy-spouting Munch (Richard Belzer) is gone, the cops-and-lawyers series fills the void with a familiar face to conspiracy lovers: Kirk Acevedo, who played Agent Charlie Francis on the universe-altering “Fringe.” Here he plays A.D.A. Barba’s (Raul Esparza) childhood friend who is arrested for attempted rape. Lester Holt also appears as himself, which should help you guess where you know him from.
“White Collar” (Thursday, 9 p.m., USA)
If you actually remember the pilot for this FBI caper, you probably also recall that the actor who played the first season’s villain, Mark Sheppard, was also the seedy lawyer Romo Lampkin on “Battlestar Galactica.” And if you don’t, you can still stare into Matt Bomer’s dreamy eyes as he makes a deal with Sheppard to free the wrongly accused Peter Burke (Tim DeKay).
