Urania knocked softly on the door of her office/library/spare room before opening the door carefully and letting herself in. She was balancing a tray delicately against her hip (a tray that held leek and potato soup, wholegrain toast, green tea, and water) and brought it over to the side table that she'd set up by the bed.
Words of comfort were not Urania's strongest attribute, nor was knowing how to talk someone into doing something for their own good without coming across as callous. Melpomene didn't need Urania's brand of callousness right now, and so Urania did what she could: she cooked (or ordered in for anything more complicated than the dozen or so meals she regularly made) and brought food and drinks to her sister throughout the day. She didn't force her to eat, or guilt her into doing it. Some of the other Muses were better at that as well. Nor did she encourage Melpomene to talk about her feelings, yet again a role better suited for another.
Urania just brought food.
"Leek and potato," Urania said after putting the tray down and smoothing her hands across her pencil skirt. "With a fair amount of paprika."
