The OA may have been one of the best and most exciting shows Netflix ever produced, and its cancelation after two seasons may have inspired a massive outpouring of fan support to try and resurrect the thing, but it looks like the show is gone for good. Now, we'll never get to know who that skin salesman was, or the story behind that psychic octopus, or learn whether Khatun was born with that Braille on her face or if it is some kind of artistic fashion choice in whatever universe she came from.

There are tons of lingering questions that will never be answered now, but the biggest one—the one that hurts the most—is the most obvious question of them all: namely, what was supposed to happen in the next three seasons?

OA creators Brit Marling and Zal Batmanglij reportedly envisioned the series as a five-season arc when they initially sold the idea to Netflix. We may have only gotten through two of the five seasons, but the plan for the last three was there from the beginning. And according to Jason Isaacs, who played Hap (and Dr. Percy, and, uh, Jason Isaacs) in the show, those seasons would've been incredible.

Isaacs told Collider in a new interview that Marling and Batmanglij had given him a taste of what's to come in the third season, and it sounded "utterly brilliant." Per Collider:

When they told me the end of Season 2, I went, “Wait, guys, are you actually sure? That sounds nuts to me. What can you possibly do afterwards?” So, they sat me down and told me, and 15 minutes later, my jaw was hanging open. I just couldn’t wait to get started making it. And now, it looks like we won’t be making it. I’m sad, not just for the fans, but for me, because I was at the front of the line. I’m such a huge fan of the show. I’m dying to see the rest of the seasons because I know they happened in their heads, and I so enjoyed and was moved by the first two.

Isaacs said that when he first found out about that final, meta twist—where OA jumped into a dimension where Brit Marling and Isaacs were both actors on a show very similar to The OA itself—his "head was spinning." He was first unsure about playing himself in the show, until he realized that there was more to the character than just his real-life persona:

It’s Hap inside of some version of Jason Isaacs, in a universe that they were going to create, so there was all kinds of fantastic potential there for that. And it’s a world in which Jason Isaacs is married to Brit Marling, by the way, which many people thought was true. They just were so smart at playing with those expectations, and coming up with things that were both interesting and clever, but also moving and human. And they changed the goalposts, all the time. Season 2 was so different from Season 1, and Season 3 was going to be very different from Season 2, as well. I feel sorry for everyone, and mostly sorry for me, that we won’t get to watch it.
