How will AMC’s shape-shifting Breaking Bad prequel wrap up its first season tonight at 10 p.m.? By once again unspooling an episode unlike the previous week’s. With Saul, er, Jimmy (Bob Odenkirk) reeling from the revelation that Chuck (Michael McKean) betrayed him re: the Sandpiper lawsuit and cost him a fancy job at HHM, something unpredictable is brewing. “This episode takes the show in a left turn that I don’t think any of us were expecting in the writers’ room, but now feels like the only thing that could have happened,” executive producer Peter Gould tells EW, noting that “what Jimmy goes through in episode 10 changes him forever, and changes his outlook on life and who he is.”

And there is your big tease for the Better Call Saul finale. Thank you for reading this post and hope—What’s that? You want 10 more hints about what to expect in the show’s season finale? Hold on a sec. [Huddles with legal team] Your honor, EW calls back to the stand Peter Gould, who will tell you everything you need to know about the final hour.

• “We’ll see some time shifts…There is a big question about who Jimmy McGill really is and who Slippin’ Jimmy really was.”

• “There is a character who is absolutely key in this episode who has been introduced, but as far as I can tell nobody out there has realized the significance of this person. This person turns out to be really pivotal in Jimmy’s life.”

• “We see many of the different sides of Jimmy McGill. We see the side of the guy who is a good lawyer, who is good with people. But then we also see that there is another side to him. Maybe now he’s going to give in to some of his worst—or—best inclinations.”

• “There is a Kennedy half dollar that is so important, I think people will be running to wherever they keep their coins and pulling out Kennedy half dollars and examining them.”

• “There is a sequence that is a throwback to old filmmaking techniques that people don’t use very much anymore.”

• “Sandpiper Crossing is Jimmy’s case, and we’re going to find out what’s really important to him and how much of what he was doing—especially in the last few episodes—was all about pleasing his brother. And if that is really what it’s about for him on a deep level, then where does that leave Sandpiper Crossing? Where does that leave his law practice? These are all big questions and I think the answers are surprising.”

• “There is loss. Jimmy McGill is not through taking punches.”

• “There is a callback to Breaking Bad that I think is hilarious. There is something very rewarding about having someone allude to an event and then actually seeing it.”

• “Jimmy and Mike [Jonathan Banks] have a key scene together in this episode. It’s not a long exchange, but it may be the most significant exchange in the latter half of the season. And in some ways, Mike is the only one who knows a big chunk of Jimmy’s story. There are people who are closer to Jimmy than Mike, but nobody sees Jimmy clearer than Mike.”

• “The end of this season is very much in keeping with the end of all the episodes—I wouldn’t necessarily call it a cliffhanger. But the end of this season makes some big, bold promises about what season 2 is going to be like and where this guy is headed, and I couldn’t be more excited by where it’s going. It’s a very provocative ending.”
