Keep in mind that the anime pilot was going to have the series end with every character killed in some method. So maybe it was meant to imply that everybody you love and care about will end up à la game of thrones. Or since the flowers are from the meadow maybe it is to show that the meadow eren and mikasa are sitting in is soon going to be riddled with blood and gore.

In the words of randy marsh: I am tired of watching people die! Of getting invested in their personalities and their back stories and watching them die!
