‘The Flash’ spoilers: Robbie Amell’s appearance and more in ‘Things You Can’t Outrun’

While the first two episodes of The CW’s “The Flash” may give you a good sense of Barry Allen’s powers, we are almost just as interested in the October 21 episode, which carries with it the title of “Things You Can’t Outrun.”

This episode will feature at least the first of possibly many appearances from Robbie Amell, who plays Ronnie, the supposedly-late fiance of Caitlin Snow. In the comics, this is the man who ends up becoming at least one half of Firestorm. We’ll have to see how that is handled on the show, but for now, you can see some details of what to expect in the attached synopsis:

“As Barry (Grant Gustin) and the team at S.T.A.R. Labs work to capture Kyle Nimbus (guest star Anthony Carrigan), a.k.a. The Mist, a dangerous new meta-human with toxic gas powers, they revisit the painful night the particle accelerator exploded and killed Caitlin’s (Danielle Panabaker) fiancé, Ronnie (guest star Robbie Amell). Meanwhile, Joe (Jesse Martin) decides to finally visit Henry (John Wesley Shipp) in jail after all these years, but things take a dangerous turn when Kyle shows up looking to punish Joe for arresting him years ago. Meanwhile, Iris (Candice Patton) and Eddie (Rick Cosnett) continue to hide their relationship from Joe.”

The mystery about Firestorm is probably up there with the mystery of Killer Frost on the list of what we are the most excited to see on this show … though we imagine that we may be waiting for a little while on the latter. There’s no real indication that the show is going to be rushing anything.
