Stuart Fails to Save the Universe episode 1's 'OG death' isn't actually shocking at all — in fact, there's an overwhelmingly obvious clue to confirm that it's not even real

Like... it's in the concept

Spoilers for Stuart Fails to Save the Universe episode 1 ahead.

Stuart Fails to Save the Universe episode 1 has arrived, and is now available to stream worldwide on HBO Max.

In short, our "starting" versions of Stuart (Kevin Sussman), Denise (Lauren Lapkus), Kripke (John Ross Bowie) and Bert (Brian Posehn) live in a reality akin to The Walking Dead, complete with Mad Max-style apocalyptic outposts and wasps that are the size of cars.

Stuart accidentally triggered this multiverse Armageddon after breaking a device supposedly built by Sheldon (Jim Parsons) and Leonard (Johnny Galecki).

Shortly after Kripke, that universe's leader, is confronted by the rest of the group, we meet our first secret TBBT cameo: Raj (Kunal Nayyar). He's basically become a doomsday prepper, working on plans on a blackboard for how to get the device working and get the hell outta dodge.

But just as quickly as we've met him, Raj is killed while the others safely teleport to... well, hopefully somewhere better. It's a bold move, and one that has shocked fans if social media is anything to go by.

However, we've been so caught up in Raj's death that we haven't considered one major detail... it hasn't really happened at all.

Only one version of Raj is now dead... and it's certainly not the one from The Big Bang Theory

Did you forget? This is just one version of Raj in one universe, meaning there's still an infinite number of Raj's out there to be found.
