Aaron Paul has discussed his final scene at the midway point of the most recent season of Breaking Bad.
The AMC drama wrapped up the first half of its split fifth season earlier this month with 'Gliding Over All', and Paul's character Jesse ended it on a crucial, fraught interaction with Walt (Bryan Cranston).
Speaking to Digital Spy about the season, Paul revealed that a crucial aspect of that scene - in which it is revealed that Jesse is now so afraid of Walt that he keeps a gun concealed during their conversation for self-defence - was not in the script, but added during shooting.
"The day before we shot that scene, Moira [Walley-Beckett], our writer, said, 'Hey, we're adding something to the start of the scene'," Paul explained.
"'We're gonna have you walk out and look like you're gonna grab something, and then at the end of the scene when you grab the bag, you're going to slump against the wall and pull out a gun. So you've grabbed that gun to protect yourself'."
Paul went on to suggest that it had been added to give the audience some indication of what Jesse's state of mind will be during the final eight episodes, which are yet to be filmed.
"That wasn't originally in the script, so they placed that in there to reveal a little bit of what is to come in the final eight, and where Jesse's at in his head," he explained.
Asked whether he has any idea about what else might be to come in the final stretch of episodes, Paul admitted: "I don't even know if the writers know.
"They just went back into the writers' room not that long ago - they're just trying to figure it out themselves. But I think it's gonna stay in the same pattern, and be the most intense season yet.
"I'm really excited, and somewhat devastated, to see how it all ends."
The final eight episodes will air on AMC in the US in summer 2013.
