This is to be expected. As an aside; it is a little known fact that Mr. Murphy was - in all likelihood - a degenerate pot farmer who experienced all manner of reversals in his quest for the greatest of buds, only to be remembered for his keen pronouncements on life, the Universe and the whole karmatic experience of fucking up his own life.
I'm sure Mello didn't mean to step on the seed pack with her stilleto heels while she and Shaun were arguing over the composition of black holes and the entire time-space continuum and gravity thingy that concerned Einstein and all those brainiacs (until this issue was successfully resolved by Murphy's Model of the Universe). Mello didn't mean to chop up the grow room in a fit of rage using Shuan's designer meat clever (that she shelled out 125 euros for in an online porn activist fund auction) when the recalcitrant seeds were found to be acting "uppity" around the help.
These things happen...
All hilarity and comedy to the side, I'm going to be paying close attention to these goings and comings. Pot is a serious subject (at least for those who refuse to believe that sobriety is a treatable condition)...
