The Flash season finale: cheat sheet

The Flash season 6 finale airs on Tuesday, May 12 at 8pm ET/PT in the US – and as usual, its home is free-to-air channel The CW. This means it can also be easily streamed on Hulu, which offers a free trial of the Hulu + Live TV package you need to watch The Flash without cable.

Spoiler alert: if you’re not fully up-to-date with The Flash season 6, you may find some unwanted surprises below. Please bear this in mind and scroll down for specific guides to watching The Flash online in countries other than the US – where the episode order may be different.

This wasn’t meant to be the final episode of The Flash season 6, of course – but the Covid-19 pandemic meant the show could only film 19 out of an originally planned 22 episodes. We’re still set for an action-packed send off, though, as this year’s Flash season finale sees Barry Allen (Grant Gustin) finally meet the Mirror Master – and their true identity might come as a surprise.

Originally an Arrow spin-off, The Flash was the second show to launch as part of the Arrowverse and quickly became one of the very best superhero shows around – as well as playing a key part in this year’s Crisis on Infinite Earths crossover.

That’s all old news now, though, so let’s cut to the chase – here’s how to watch The Flash season 6 finale online and stream episode 19 of the hit Arrowverse show no matter where you are right now.

Can I watch The Flash on Netflix?

Yes – but only if you have access to Netflix Canada

It’s the one major country where all six seasons of The Flash, including new episodes like tonight’s big finale, can be streamed on the popular service. Which is great news for those living in the Great White North – and terrible news if you happen to be anywhere else.

That’s because geo-blocking will almost certainly prevent you from watching the shows and movies you normally would at home, even if you pay for a Netflix subscription.

Fortunately, there’s an easy solution – using a VPN. This clever bit of software allows you re-point your computer back to a location in Canada so you can stream your local Netflix catalogue just like you would from the comfort of your couch. 

Of the many options, our testers rate ExpressVPN as the best option due to its ease of use, fast speeds, and security features – and better still, you can get a 49% discount and 3 months extra FREE if you sign up to ExpressVPN today.

How to watch The Flash finale online in the UK

Sky has the rights to The Flash in the UK, but it’s a few weeks behind the US in terms of airing new episodes on Sky One. The second half of The Flash season 6 started on Tuesday, March 31, so while you can tune in at 8pm tonight, you won’t be getting the finale like you would in the States – but rather episode 15.

Nevertheless, Sky subscribers can watch The Flash season 6 via the Sky Go app, which is available to them at no extra charge on Android, iOS and PC/Mac devices. The only catch is that anyone new to the series will find only season 4 and 5 are available to watch on-demand.

Those who don’t want to commit to a lengthy Sky contact aren’t left behind, either, as they can snap up a superb value Now TV Entertainment pass – it costs just £8.99 a month and there’s even a FREE 7-day trial on offer right now. Like Sky Go, you’ll get new Flash season 6 episodes to watch just after they drop on Sky and seasons 4 and 5 in full on-demand.

If you’re currently out of the UK for whatever reason and can’t access your usual streaming service, remember you can always just grab a VPN and point yourself back to Blighty to watch your favourite shows as usual.
