That Ends Wells

Synopsis: In ‘All’s Wells That Ends Wells’. When an experiment to save Barry’s speed backfires, Nash Wells searches for a way to save The Flash and comes up with a dangerous plan. Meanwhile, Iris makes a startling realization inside the Mirrorverse and Cecile faces off with Rosa Dillon.


The Story

‘All’s Wells That Ends Wells’ is a bitter-sweet episode that provides a farewell to Nash Wells. With Barry’s speed near enough depleted, it is becoming more and more imperative that he gets his speed back. Especially given that Mirror Master aka Eva McCulloch is still at large. And Barry’s wife Iris is still trapped in the Mirrorverse.

At Star Labs. The Council of Wells reveals to Nash that with them being Particles that are drawn to him. They can be used to power the machine that will give Barry his speed back. The only catch is. Nash Wells will have to sacrifice himself in order for it to work.

At the police station, Cecile offers to defend Rosa Dillon aka The Top in exchange for any information that she can provide in regards to Mirror Master’s plans. But to get the information she needs. She has to use her empathy powers in a rather unorthodox way.


The Acting

It goes without saying that one of the best actors on The Flash has always been Tom Cavanagh and if this is indeed to be his swansong. It’s a pretty strong episode for him to step out on. For 6 seasons. Cavanagh has given us various incarnations of Harrison Wells and in this episode, we get to see several of them. And in a fairly fun twist. We also get to see Barry Allen channel a few versions of Wells when the first stab at an Experiment to bring his speed back goes awry. Which of course allows Grant Gustin in his role of Barry Allen to do various variations of Cavanagh’s comedic creations, but sadly not quite as good as Cavanagh can do them.

Carlos Valdes is absent from this episode because Cisco is on his travels trying to find a way to help Barry. But filling in for him is Chester P. Runk who is played by the fantastic Brandon McKnight who is still really stoked to be a part of Team Flash.

The final mention should go to Efrat Dor who manages to do quite a lot with very little in the way of screen time as Mirror Master. Obviously, this episode is just one of a few that will wrap up her storyline. But I’m pretty sure it is all going to be happening in the next few weeks.



Not a bad episode to start back with. But also somewhat bittersweet given that we lose what has been a key character in Nash Wells. I only hope that the resolution to this story arc is worth the huge sacrifice of what has been such a huge part of the show’s mythology. So I guess all is wells that ends wells.
