XDC, Walt's transition is mesmerizing, isn't it? Found a great photo which demonstrates how he changed over the series. It doesn't reveal much, but I'm gonna post it as a spoiler because I'd hate to give away any details to those still watching!

Afs, you know me far too well! I didn't realize those actors were from the Downton Abbey show since I don't watch that one, but it was funny regardless getting to see a prim and proper Walt as a tea kingpin.
