Theme Three: Same Color as Your Eyes
"Put it down, Roy." Maes reasoned gently.
"I can't." He muttered softly, cradling the bottle. He gazed into the depths, as if it would disappear and reform into the thing he needed most.
"Drinking won't bring her back, Roy. Nothing will. She wouldn't want this." He said softly, reaching for the bottle.
Roy clutched it to his chest, guarding it with his life. "It's not that." He said. "It's… it's the same color as her eyes. It's always been… the same color as her eyes…" Maes looked at the bottle. Surely enough, it was a unique sharp shade of bronze amber. Roy looked at it lovingly. "Every time I drank… it was always like… like she was there. Like she was inside of me…" He took a glass from his side and poured the liquid into the crystal. "We made love once." He said to no one in particular, trying to make sense of himself. "Just once. We were talking… and we felt like neither of us was truly alive, you know? So we just wanted to feel something…" He took a deep swig of the stinging liquid and he could have sworn the day afterwards that he could feel soft warm arms encircling his shoulders.

NO.
