there might be flashbacks to what happened at Gray Matter (we still don't know what Walt actually did there), which is the real root of Walt's determination to become the drug lord he is. The individual elements might play roles throughout, i.e. I did A level Chemistry (~ 1st year of college for you Americans), and I'm sure the there's no common compound with all of those metals (only thing I can think of that combines several metals alone are superconducters.)Īs you've pointed out, FeLiNa is made up of elements, which will probably be highlighted in the opening credits - such an aesthetically pleasing title for the finale! - so I'm hoping this episode will have some 'Yeah, Science' moments (though probably not as joyous ones as such). That's such a great idea - I can't believe I missed that.
