Sienna is almost like a sister to Tegan, however, they like to fight a lot. It's usually over dumb things but sometimes they get into serious, open fights. Sienna doesn't trust anyone except the ones in the alley. Frankly enough, someone has reported her for theft an that's why she keeps an eye out for everything. Likes gossiping but hates getting into drama.

Has normal girl voice but it feels soft to the ear.
