Piper Smith: a SuperWhoLocked Potterhead-ed Trekkie, lesbian, and black Scott.
Thalia Noble: a WhoLocked Potterhead, an asexual, and American Latino. Despite their sexualities, Piper is more than a little interested in Misha's angel blade, they both are pretty sure Cumberbatchsexual is a thing, and even though not many people can pull off a velvet suit, they'd pull off David Tennant's. ;)
