It’s almost the weekend. Yay! I’ve missed a few shows this week so I’m looking forward to embracing some laziness and catching up on The Blacklist, Sirens, and Dig tomorrow. What’s sitting on your TiVo? While you think about what you’ll watch first, peruse today’s round-up of TV news. We have photos of Lady Sif’s return to Agents of S.H.I.E.L.D., character photos for Salem Season 2, and celebrity tributes to Mad Men.

Memory Problems. Jaimie Alexander’s Lady Sif is returning to Marvel’s Agents of S.H.I.E.L.D. on Tuesday’s episode, “Who You Really Are.” However, she’s not quite her usual Asgardian warrior self. She’s lost all her memories and doesn’t recognize Coulson or anyone else. A new poster by artist Marcos Martin was revealed at Entertainment Weekly and shows Sif’s return and also hints at Skye dealing with her new abilities. The poster is available at the Marvel Shop. And if you need a further S.H.I.E.L.D. fix, visit Comic Book Resources to see a gallery of photos for the upcoming episode.

A Wanderer Appears. A new character was introduced in last week’s episode of Vikings. Harbard, played by Kevin Durand, showed up in Kattagat and in a way, he was expected. Helga, Siggy, and the Queen have all had dreams about his arrival. Clarke talks to Durand about the role for Nerdist.

Beeing Successful. The Daily Show correspondent Samantha Bee is leaving the show to head her own series at CBS. It doesn’t have a title just yet but was created by Bee and her husband Jason Jones. Production for the new show doesn’t start until the summer so Bee will continue to appear on The Daily Show occasionally which is nice since she’s been around the longest of the regular correspondents.

Tipping a Hat to Mad Men. AMC’s Mad Men is almost over. Sigh. The last half of the seventh and final season premieres on April 5, and Don Draper, Peggy Olson, and everyone else will be taking a bow. AMC is starting the good-byes with a series of tribute videos from the likes of Kevin Pollak, Gary Oldman, Sarah Silverman, and more. You can watch all 19 tributes at AMC. [TVLine]

Action Heroes On TV. The Expendables isn’t the most original of franchises, but it is a lot of fun. The three films in the series so far have rounded up several action heroes, mixed in some humor, and created a recipe that fans respond positively to. Fox is going to attempt to translate the magic to television. They’re developing an action-drama “event” series called The Expendables. It only has a script order right now, and there are many more steps to take to get it close to a project that might happen. Sylvester Stallone is on board as executive producer. [Nerdist]

Which Witches? WGN America’s Salem has some of the richest and most interesting costumes on television, and they’re on full display in new character images for Season 2. The portraits show new looks for Mary Sibley (Janet Montgomery), John Alden (Shane West), Tituba (Ashley Madekwe), and more–like Lucy Lawless. Check out more photos at IGN.

The Language of Angels. Arrow’s John Barrowman has signed on to executive produce and star in a television miniseries adaptation of The 49th Key. The first part of the story by writer Erika Lewis and artist J.K. Woodward is in issue 273 of the sci-fi/fantasy comics magazine Heavy Metal, and it’s inspired by legends about Enochian magic which is based on the secret language of angels. And if the word “Enochian” sounds familiar to you, it might be because you watch Supernatural. [The Hollywood Reporter]

Do you think an Expendables television series would work as well as the films? Let us know in the comments.
