It was recently confirmed that the Marvel properties which have already aired on Netflix will remain on the online streaming service despite the fact that Disney is launching its own platform. That obviously includes The Punisher and with season two on the way, some new character breakdowns have surfaced which point to the show adapting Garth Ennis' acclaimed "The Slavers" story arc from the mid-2000s.
According to That Hashtag Show, Marvel is looking for two series regulars in the form of "Annie Bier" and "Kim Davis." For Annie, they want an 18 year old female to play a 16 year old and she's described as, "someone who is used to the streets and is both scrappy and aware of her environment." Kim, meanwhile, is going to be in her mid-30s of any ethnicity and will be a therapist in the series.
The site speculates that season two will adapt the story from Ennis and here's an explanation why:
"ANNIE BEIR, the street-smart scrapper, could be an analog to Viorica, the young girl whose life Castle saved and whose story led him to discover the sex slave ring run by Vera Konstantin and Cristu Bulat. In that story, Castle enlisted the help of a social worker, Jen Cooke, who had worked with Viorica, to learn about the slavers and take them down. In this case, KIM DAVIS could be the Jen Cooke of the story."
It's also noted that The Punisher may be looking to cast Detective Martin Soap, a character first introduced in Ennis' "Welcome Back, Frank" story arc in which he was a member of the Punisher Task Force. It seems we'll have to wait and see but if casting is already underway, the show could return as soon as next year and we'll no doubt start hearing additional casting information very, very soon.
