A carefully maintained line of labeled flowers reveals an unknown woman's presence at Carl's father's trailer.
Along the clean south wall of the trailer, pots contain alliums, daffodils, asters, hyacinths, and other flowers. The largest pot holds round purple allium clusters.
Each container has a small handwritten plant label. The writing is elegant and feminine, and every plant appears deliberately tended.
A nearby shed is neatly organized with gardening supplies and bags of soil. Carl knows his father would never have maintained such a garden and recognizes the implication of another resident or visitor.
A neat row of labeled flower pots against a neglected trailer, led by large purple alliums.
The flower row is evidence that the selected memory contains a woman unknown to Carl and something the dungeon specifically wants him to notice.
