But what about the ricin? I never forgot the chaingun. I never forget chainguns.

If he has a chaingun and he's going after the nazi's, what's he need ricin for? TO KILL JESSE!? No, that makes no sense. Jesse gets the chaingun. Because it's not like Walt can act buddy buddy with Jesse and slip him the ricin. Jesse hates Walt 4ever. Maybe Walt just meets with the nazi's because Jesse isn't cooking right. Like you said, the nazi's are threatening to get the fam. So now Walt's like...hey bros, chill, I'll cook. Then he gives them the ricin. And then TWIST! Walt uses the chaingun on his family.

I've got it.
