Peter painfully learns that someone close may have betrayed him and Claude (guest star Christopher Eccleston). Matt's world spirals out of control when radioactive man Ted Sprague (guest star Matthew John Armstrong) and Hana Gitelman (guest star Stana Katic), a fierce young woman with "wireless" mental abilities, drop into his life. After blood is spilled, Hiro makes a difficult decision about his mission. Claire is unable to contain her anger at her father. Tawny Cypress, Santiago Cabrera, Noah Gray-Cabey, Ali Larter, Adrian Pasdar, Sendhil Ramamurthy and Leonard Roberts also star. Jimmy Jean-Louis, Lisa Lackey, James Kyson Lee, Zachary Quinto and Cristine Rose guest-star.“Somebody flies, somebody dies,” somebody whispers during each of those promos. Someone may indeed die in this week’s episode, titled “Unexpected,” but we’re still two weeks from losing a regular on March 5. What we do get tonight is Stan Lee, creator of Spider-Man, The X-Men, Hulk, Daredevil and a host of other classic Marvel icons, who plays a bus driver who runs into Sylar. What comes beyond tonight, we cloak in the text invisible: * 1.17 (Feb. 26), titled “Company Man,” will see Matt and Radioactive Ted have a sit-down with Jack Bennet, and we learn much about Jack’s past via lots and lots of flashbacks – including one depicting how he came into possession of Claire. * 1.18 (March 5), titled “Like Any Parasite,” is the one in which Peter, Nikissica, Micah, Jack, Mohinder or Simone gets killed. It’s also the episode in which Peter finally meets Linderman – who, says TV Guide’s Michael Ausiello, may or may not be played by Malcolm McDowell. We also meet sexy Candice Wilmer (“Stick It” star Missy Peregrym), whose superpower appears to be that she’s impossible to resist. * 1.20 (TBD) looks likely to take viewers to the time of FutureHiro. 9 p.m. Monday. NBC.
