'The Walking Dead': Andrew Lincoln reveals his best day ever on set

We’ve been asking a bunch of cast members of

about their favorite days ever on set of the show, and we’ve gotten some pretty great stories in return. But we saved the best for last. It comes courtesy of Lauren Cohan (who plays Maggie), and you may never watch the scene the same way again after hearing what was really happening while filming.

, Cohan went back to season 5 and the aftermath of the big bus crash. We’ll let her pick it up from there. “One of my favorite days was during the “GREATM” episode when the six of us were on the road and the bus went up in flames,” says Cohan. “And the flames were much bigger than we thought they were going to be; still safe, but much bigger than we thought they were going to be.

And the rain started coming down and melting the hair dye out of his hair and I just started laughing. And in the scene I’m actually going [makes laughing and grimacing face], but it’s that ridiculous laugh where you

you’re holding it in. And I’m nudging Josh because I don’t think it’s safe anymore, and I’m nudging him to leave. If you watch the episode you can actually see us just trying to hold it together, and

But that was not it for McDermitt. “And then we run away,” Cohan continues. “And then Christian [Serratos, who plays Rosita] goes to push him. I think Josh gets a lot of flak. I’m pushing him away from the flames, and then he walks away, and then Christian pushes him. It’s all
