My Best Friend

Right across the hall... there she was. That one girl, with her blue scarf hanging on either side of her pale neck, and with her long, dark hair and the sweetest smile the world have ever seen. Based on a tumblr post/prompt. Lydia and Allison (no femslash). Canon divergence. Reincarnation-sort-of-thing. Post Nogitsune, post s3B, pre-s4.
