The series arc has been completed. The one arm man has been caught. Kind of...
Although Rick himself doesn't have the Szechuan sauce yet, Justin Roliland himself does. He recently tweeted that the received a very large container of the stuff direct from Mickey Ds themselves.
The note sent with it says:
We finally did it. It took months, but we’ve finally brought back some Szechaun Sauce.
We’ll spare you the physics, but turns out, Dimension C-1998M is a dimension where it’s always 1998. 1998 every day. No smartphones, no social media. It’s a weird, scary place. But they’ve got Szechuan Sauce on the regular menu.
So here we are with some precious cargo–the Szechuan Sauce you remember and some sou-venirs from the some of the dimensions we tried along the way.
We wish we could’ve brought more sauce though, but we couldn’t risk keeping the a portal like that open. Think about it, if you knew in 1998 that McDonald’s would have All Day Breakfast in 2017, would you really want to stay in 1998? Of course not. If we left the portal open, we’d have puka shells, bucket hats and boy bands as far as the eye could see. It’s too risky, even for sauce as delicious as this.
A few lucky fans will also get to experience the glory, but the first bottle in this dimension is for you.
The labeling on the container also reflects the idea that the sauce was brought in from an alternate dimension.
Three big things for me here. First, what will this mean for the show? I mean the great quest has been fulfilled. Second, I want to know how the everyday man gets their hands on some sauce. The note says "a few fans will also get to experience the glory". I can't wait to see how. Finally, props to McDonald's to realizing what an opportunity this really was for them and properly hopping on board. Not enough places are willing to do such a thing. Good for them.
Wubba lubba dub dub!
