I've been watching as much of the Breaking Bad marathon as I can (even though I missed most of Wednesday/Thursday). Dammit why wasn't I watching this show all along! Anyway ...... I just watched the 2011 season finale (where Brock got poisoned, they destroyed the meth lab, and Gus got blow'd up ... ). The very last scene was a close up shot of a potted Lily of the Valley plant in Walt's backyard. Was that supposed to be an implication that Walt was the one who poisoned Brock, or that maybe he tried to poison Jessie but somehow Brock got it instead? Or was it just one of the weird/quirky things they seem to do on this show?
