Single royalty by birth both on the outside and the inside truly fits Pipp Petals, whereas, single non royal by birth both on the outside and the inside truly fits Zipp Storm.
I truly prefer Pipp Petals and Zipp Storm as only children/unrelated non-relatives/non-related strangers as opposed to them (Pipp Petals and Zipp Storm) as forced canon twin sisters/relatives.
Zipp Storm should’ve been the canon younger sister instead of Pipp Petals or better yet, an only child, whereas, Pipp Petals should’ve been the canon elder sister instead of Zipp Storm or better yet, an only child.
