Marcus (Earth-Prime)

"There's this quote from Plato that's always stuck with me. He said that plants grow their roots towards the earth, but people, we're heavenly plants, meaning that our roots, they grow upward, towards our heart. But those roots, they need to be cared for, tended, like any plant... Or your heart will break before it even has a chance to grow."
