To fans of the time-travel genre, Raimy Sullivan (Peyton List) is pretty much a perfect example of what not to do when you mess with time.

Much like Barry Allen (Grant Gustin) on “The Flash,” Raimy has decided that she’s going to fix her life, save her parents and save the day with her newfound time-traveling radio. In other words, screw the consequences!

One thing we appreciate about “Frequency’s” take on time travel is that they’re doing an excellent job of preserving causality, despite their many timelines. For example, in the pilot we saw the Nightingale Killer hone in on Ramiy’s mother, Julie (Devin Kelley) when she bumped into him in the elevator during her hospital visit with Frank (Riley Smith). A visit that never occurred in the timeline where Frank died, thus ensuring Julie’s survival.

Next, we see Raimy’s directive for Frank to look into Thomas Goff (Michael Charles Roman) lead to Maya Gowen’s (Alexandra Metz) escape, which presumably never happened even in the new timeline. But like a totally demented butterfly effect, Frank’s visit ends up freeing Maya, leading Goff and his family to move away from the estate Raimy had just visited a day earlier.

To drive the point home, we learn Julie is the one to introduce Raimy to Daniel (Daniel Bonjour) in the original timeline, which obviously never happens if she dies in 1997. That means bye-bye cute boyfriend and impending proposal.

This show is being very direct about cause and effect and how it can steer the timeline in a new and dangerous direction, which is a major bonus in the time-travel column. There’s nothing worse than murky explanations for what causes changes in the timeline and why.

We just wish Raimy hadn’t decided to stop being so reckless at the very moment her dad needed her to prove he wasn’t totally insane. Kind of a buzzkill.

One thing that seems like a bit of letdown is the fact that we now know definitively who the Nightingale Killer really is.

In the original film, it didn’t take very long for Frank to track down this killer thanks to future knowledge of when and where he would strike, but Raimy seems to hone in on Goff right from the start. In less than 2 episodes, we’ve solved the mystery of the Nightingale Murders, even if Raimy and Frank haven’t quite caught the bad guy yet.

There’s still lots of plot left — and her mother’s murder to stop — but it feels like this reveal was rushed way too soon.

If, heaven forbid, “Frequency” doesn’t get a full 22 episode order this year, then the break-neck pace of the plot will make more sense. However, if they do, it’s going to be interesting to watch them stretch this hunt for Nightingale out for 20 more episodes now that the biggest part of the mystery is essentially solved.

“Frequency” airs Wednesdays at 9 p.m. ET/PT on The CW.
