[Saul gets it. If there's one thing he's figured out this week, it's that this is never going to stop. Whether Walter's here or a million miles away or dead, this will not stop. And that breaks his heart.

Jesse keeps talking; Saul grows more nervous. He's halfway to a full-blown panic attack when Jesse finally comes out and says it — you'd never do that — and his hand curls tightly into the fabric of Jesse's shirt collar. It's not a threatening gesture at all. It's more like he desperately needs to hold onto something lest the floor slip out from under him.]

I did. I helped him.

[The way he sees it, none of them are innocent. And if the truth is going to come out, it might as well happen now — Jesse was convinced that Saul had helped Walter in the first place, anyway, so what difference does it make if he just admits it?

All the difference, probably.

He doesn't let go of Jesse as he speaks because he's afraid that any distance between them will allow Jesse the space needed to beat the shit out of him. Kill him, maybe. How should he know? Nothing would surprise Saul, at this point.

It's not like he doesn't deserve it.]

But it wasn't the ricin! He didn't — it was some flower, right? He didn't use the ricin, Jesse. I gave it back to him! He tricked you, and if I didn't do it, he — you know he would've killed me! The kid too, maybe! I didn't know how sick he'd get! Walter said — he said it'd be like the flu, just the flu, I swear!
