Bellatrix Lestrange and Ginny Weasley
Really, Bellatrix Lestrange and Ginny Weasley were the same. They would never be able to get to know each other though, so fortunately for the both of them this was something that they would never be made aware of. They were in wildly different worlds, each others carbon copy in their own. Both vied for the affections of their saviour and leader yet were rejected, looked down as nothing more than their best friends sister, or a loyal inner circle member. Instead, they had partners who their family found much more suitable, whether it be a quiet Ravenclaw called Michael Corner or Rodolphus Lestrange who had been betrothed to her at birth. They were always the one in the family who got the most attention; Ginny because she was the only girl and the youngest and Bellatrix because of her overly enthusiastic embrace of the dark arts and family values. Maybe that attention wasn't too good for either of them. Passion exuded both of them, it just so happened that Bellatrix happened to use it in a different way to Ginny, not that Ginny didn't have a fiery temper inside her too, she just unleashed it less often, and left less destruction in her path. They were the same. Just one was good and one was evil…
