XS Returns To Help Barry In New THE FLASH Episode Stills

The Flash is currently running at top speed towards the end of season 8. Just six more episodes remain before the series heads off in to the summer hiatus before its ninth (and final?) season.

After taking a breather to mourn the loss of Killer Frost (Danielle Panabaker) last week, this week will see Jessica Parker Kennedy returning for a guest spot. It looks like Nora will be dropping in from the future to help deal with either a new looming threat or Iris’ (Candice Patton) lingering time sickness.

The full synopsis for “Into the Still Force”, directed by showrunner Eric Wallace, reads:

The Flash (Grant Gustin) gets an assist from XS (guest star Jessica Parker Kennedy). Meanwhile, CCPD enlists Chester (Brandon McKnight) for help when a mysterious device is found at a crime scene. 

Here’s a look at the full gallery:

The Flash stars Grant Gustin as Barry Allen/The Flash, Candice Patton as Iris West-Allen, Danielle Panabaker as Caitlin Snow, Brandon McKnight as Chester P. Runk, Danielle Nicolet as Cecile Horton, and Jesse L. Martin as Joe West.

The series airs Wednesday’s at 8 pm on The CW.
