Precinct TV: This episode is an incredible challenge—it’s the Blindspot season 5 finale, and the series finale, plus the 100th episode. How did you handle all of these benchmarks in one episode?

Martin Gero: Honestly, it was kind of a relief to do them together, as opposed to having to do a 100th episode and then a finale within the same season.

I worked on the show Stargate Atlantis way back when, and its finale was also its 100th episode. So there’s something really nice and round about it. And especially for an episode that is doing so much looking back—I think the 100th episode is typically the most reflective time in a show’s life, and so is the series finale, so it really lined up.

PTV: How much did Blindspot wind up influencing or affecting you personally? Did you take things you learned from this experience forward into the new projects you’ve worked on since, or how emotional is it just knowing you’ve told this complete story?

MG: it’s impossible to sum up the impact that this show has had on my life. Both personally and professionally, it’s something that I will be forever thankful for. In many ways. It’s the first interaction the fans had with my work. And so, I’m deeply thankful for it.

But mostly, a TV show is made up of people, and I’m just so thankful for all the people that are now going to be in my life in a semi-permanent way, even though the show’s over.

PTV: Early in Blindspot‘s run, you talked about the future of the show and planning ahead past the first season. So without giving anything away, how much of what we’ll see on Thursday is the ending that you had in mind back then?

MG: Whether you’re writing a novel or a TV show, I think you need to know the direction you’re going, but be open to the happy accidents, and in the case of a TV show, the enormous amount of creative talent that is around you to inform and grow in different directions.

So there are pieces of the finale that, weirdly enough, have been in our minds since the very early days of Season 1. But it grew and evolved as people had better ideas over the course of five years, as the show grew into something even bigger and crazier than I could have ever imagined.

There are moments that you’re like wow, that’s nuts that that’s been there from the beginning. And then there are pieces of it that I’m like it feels like we planned that from the beginning, even though that was something that organically came only about a year ago.

The Blindspot series finale airs Thursday at 9:00 p.m. ET/PT on NBC. If you’re able, join the cast and crew in supporting The Actors Fund at actorsfund.org/blindspot.
