What did he/she do in December?: She was a trial to me-- I mean. She responded to Miwako's post about Santa, wondering if Santa could bring her an entire person for Christmas! Miwako assured her no, that wasn't possible - but then Simon showed up a day later. Nia was briefly flabbergasted at his sudden twentysomething-ness, but attached herself to him regardless. That same day, she talked to Yuri, Flynn, and a cat. Later, Oz and Break told her about truth or dare, she helped a haro find his friends, and watched a movie in the shelter - speaking to Simon, MOMO, Shinwoo, Setsuna Zelda, and someone else I'm likely forgetting. :( It's me, not you.
Then she asked the entire prison about sex.
Any plans for him/her?: Eventual canon update I have to see about, but not for a while yet. She'll just keep being Nia in the mean time.
It's the same old year in Marina. How would your character celebrate the passing of a new year back home?: "What is a year?"
