solitary man atop a hill in Cardiff, departing. This scene of "going away for good" against the backdrop of the city he has long protected, hints at the death of the Captain Jack persona; in Porter's words, "the immortal captain "dies" at the top of a hill in Wales at the conclusion of the "epic" miniseries", "epic" traditionally being the genre of heroism. The American political blog Daily Kos states Jack "can certainly be characterised as a Byronic hero, a tragic figure with a streak of melancholy, heroic yet misunderstood, bold yet rash. Most importantly, his sexuality is one single aspect of a much more complex, flawed character." G. Todd Davis examines the ways in which Jack conforms to the Byronic hero character trope. Physically, he identifies Jack as dark-haired and strikingly handsome, with masculine physique; he is intelligent and aware of it, to the point of a superiority complex; he demands unquestioning loyalty, has guilty secrets in his past, and is self-sacrificing. For this, Davis lists Jack alongside Milton's Satan from Paradise Lost, Shelley's Prometheus, and also Angel from Buffy, amongst others. As a show, Torchwood is highly intertextual. The consequence of this is that many sides of Jack are shown across various media. One commentator feels that this emphasises Jack's pivotal place in the development and change of modern science fiction heroes. The character's unexpected popularity with a multitude of audiences, would later shape his appearances both as a traditional "action hero" and as a positive role model for younger viewers. Barrowman also remarks that "The beauty of Captain Jack, and one of the reasons why I think, as an actor, I've landed on my feet, is that he's popular with one audience in Torchwood and with another in Doctor Who." Moral ambiguity In several instances in Torchwood, Jack displays no qualms about killing a person of any species, which within Doctor Who, allows Jack's character to act in ways the lead character cannot. Barrowman remarks, "He'll do things the Doctor won't do ... [such as] fight. Jack will kill. And the Doctor, in a way, knows that, so he lets Jack do it. I'd say Jack's the companion-hero." A flashback in the third series of Torchwood shows Captain Jack sacrificing twelve children to aliens in order to save millions of lives. Davies feels that the third series of Torchwood is a "tale of retribution and perhaps redemption"
