Captain Jack on his way to who

Capt. Jack Returning To WhoJohn Barrowman, who plays Capt. Jack Harkness on the Doctor Who spinoff series Torchwood, confirmed to SyFy Portal that his character will return for a multi-episode arc during the upcoming third season of Doctor Who. "I will be in [season] three of Doctor Who," Barrowman said in an interview. "I will be in the last three episodes of four episodes, and the scripts are being written as we speak, because I just got a text from [Doctor Who executive producer Russell T. Davies] telling me that he's finishing the script [in which] Jack returns." Barrowman first appeared as Capt. Jack in the Doctor Who episode "The Empty Child," and remained on the show through the end of the first season. He later reprised the role in Torchwood, which premiered in October and is currently airing in the U.K. on BBC Three. Barrowman didn't reveal the details of his reappearance on Doctor Who, but did rule out the possibility of any future crossovers on his new show. "You will never have Who crossing over into Torchwood," he told the Web site. "Doctor Who is for children, is a base for family viewing and children. Torchwood is not. The only person that will cross at this point will be Jack going back and forth, because Jack has a different persona in Doctor Who [than] he does in Torchwood, if that makes any sense. He's darker because of his circumstances, and he'll change again when [he] comes in, or he might be darker when he comes back in Doctor Who." The first season of Torchwood wraps up in January. Doctor Who returns for a Christmas special, "The Runaway Bride," which airs in the U.K. on Dec. 25, before beginning its third season next year.
