The song Reid and Maeve dance to at the end is "Sleepwalk" and the lyrics make this a perfect song choice. "I sleepwalk cause I lost you" "Sleeptalk cause I miss you while the memory of you lingers" "The night fills my lonely place, I see your face, I know I miss you so, I still love you" etc even though it was instrumental, this song captures Reid's anguish of missing Maeve and being hesitant to allow himself to dream of her.
Solanine is found in all members of the nightshade family, eggplants, potatoes, tomatoes, peppers (bell and chili), mandrake, and many other species.
Unripe and over ripe specimens usually contain the highest (ie most toxic) levels of solanine, eg. unripened tomatoes, and over ripe sprouting potatoes. Which is why these foods are the usual source of solanine poisoning.
The rule of thumb with those plants is; if it's green it's poisonous.
