Breaking Bad, ask and ye shall receive (see below for the requested map). Also, there is nothing to defer, we're in agreement, and besides, even if we weren't, the great thing about discussing ASOIAF theories that haven't been set in stone by the author yet, is that there is no wrong answers, it's all just opinion. That's what makes this book series so fantastic, it generates a lot of fan interest and discussions regarding the vast possibilities regarding the mysteries in the plot.

If you have an Android or Apple device - Ipad/Ipod/Phone/Tablet/whatever, there is a free app called "World of Ice and Fire" which has a fantastic interactive map as well, integrating many characters, events, and the like to a map of the entire world of A Song of Ice and Fire.

It was a large risk on her part if she indeed was the culprit, to poison and kill Joffrey prior to or even during the wedding, as by Westerosi law, unless the wedding is consummated - this is why their custom of "bedding" of high borns is so important, to ensure that the couple actually does the deed - the marriage can be set aside easily by both religious and legal authorities. So, technically Margery is NOT the Queen at that moment in time when Joffrey chokes and dies, as they hadn't done the horizontal mamba yet. I'm sure the Tyrells involved in the plot, if they in fact were, were fairly certain that they could convince the Lannisters to marry Tommen to their beloved Margaery in order to honor and keep their critical alliance intact, but again, as you pointed out BreakingBad, it was a pretty huge risk. This very point is one of the reasons detractors of the theory that the Tyrell family killed Joffrey base their arguments upon.
