River Tam (Summer Glau) had a great character arc throughout Firefly and its movie sequel, Serenity - but what happened after the final credits rolled on the film? Initially presented to TV viewers as an enigmatic body in a freezer, River was revealed to be a teenager on the run from the powerful Alliance. Born with a genius-level intellect, River became mentally unstable and developed erratic psychic powers after the government conducted brutal experiments on her without her consent. She was eventually rescued by her brother, Simon Tam, before sneaking aboard Malcolm Reynolds' spaceship, Serenity, starting the events of the TV series' pilot.

Initially airing in 2002, Joss Whedon's western-inspired space opera Firefly was tragically cancelled after season 1; however, the show quickly attained cult classic status, with River Tam establishing herself as a fan favorite. River often spoke in riddles and her actions appeared inexplicable at first glance, but over the course of the show, she demonstrated her value to the team countless times and gradually forged connections with the crew. These relationships served her well in the 2005 cinematic follow-up, Serenity. In a film largely centered around her, River became marginally more stable and better able to control her psychic powers. After dealing a massive blow to the Alliance and earning their ire yet again, the film ended with River piloting Serenity and the rest of the remaining crew off into the dark unknown. But if there's one thing that loyal Browncoats know, it's that you can't stop the signal.

Both River and Malcolm Reynolds' journey following Serenity would continue through canonical comic books. Two one shots, Serenity: It's Never Easy and Serenity: The Warrior and the Wind, ease fans back into the world. But the real story picks up six months after the events of the film in the six-issue series Serenity: Leaves On The Wind which finds River and the rest of the crew still on the run in the far reaches of space. After second-in-command Zoe is taken hostage by the Alliance, River helps psychically interrogate an Alliance soldier to find Zoe's whereabouts and save her. In the course of the journey, River also learns there are other young women experimented on like herself and manages to rescue a fellow test-subject named Iris.

Serenity: No Power In The 'Verse, a six-issue series, continues River's story. Christened "Auntie Wiver," by Zoe's adorable toddler, the child of the tragically killed Hoban "Wash" Washburne, River appears well-adjusted and well-loved. That is, until Kalista, a former psychic test-subject briefly seen in Leaves On The Wind, appears and kidnaps River. Claiming that she is rescuing River and returning her to the experiment sisterhood, Kalista brainwashes her into fighting on behalf of the Alliance. Mal and the other members manage to rescue her, but both the trust of the other crew-mates and River's trust in herself remains fragile.

Current comics have returned to chronicling the lives of the crew-mates before the events of Serenity. However, the future of the comic book series is wide open and with a proliferation of spin-offs recently, it's certainly possible that River could get more time to shine. Additionally, there may be renewed hope for fans of River Tam as Fox has expressed interest in possibly reviving the world of Firefly and Serenity.
