I keep trying to picture how far in the future we got when Walt grabbed the ricin from the wall plate.
As far as Walt knows Jesse is dead, after he deals with the rest of the Aryans he'll get a surprise as to who the new cook is.
I don't know how this doesn't end with Jesse killing Walt (unless it's Todd that does it in retaliation for Walt attacking the Aryans ie Todd's "family")
