Ohh, the colors in this one! So descriptive, and so much beautiful imagery! If I am not reading too much into this, the whole idea of "glass from sand" ties in directly to Anakin and Padme. It's at that very lakeside that he tells her how he hates sand. But she sees how rough, coarse sand can be fashioned into something exquisite, like how Anakin can be transformed from the surly teen from the outer rim to the respected Jedi who wins her heart.
