4) Nods To Hellcat
Other than getting the chance to kick some ass later in the series, Jessica Jones doesn’t exactly set up Trish Walker’s transformation into Hellcat. However, it does reference it in a number of ways.
For example, her red wig when she’s “Patsy Walker” in that cheesy sounding TV show is a clear nod to her comic book counterpart’s appearance, while that series in general appears to be a nod to the character’s very early 1940s set adventures when she starred in romantic stories and the like (it wasn’t until decades later that she was reimagined and rebooted as Hellcat).
As Trish’s powers are rooted in mysticism, it’s certainly possible that she’ll get them somewhere down the line as Daredevil and Iron Fist further explore those themes. For the time being, though, it definitely appears as if her role in Jessica Jones will be much different than that.
