Oh, this is lovely. You really captured their cute-cranky dynamic in a nice, subtle way, and I love how Rue warms ever-so-slightly to Duck by the end of the ficlet.

I loved this line:

Rue froze for a second and pursed her lips. Most of the compliments she heard lately that she didn't tell Mytho to tell her came from Duck. Those also were the most sincere.

It says so much! I love these two together, and this darling little fic is a great example as to way.
