I think she's an 8 because if you look at her past, there is all this crazy stuff (like being a circus attraction). she strikes as the stereotypical "nurturing, sexual and calm but secretly a bad ass" 8w9 female. now that you mention 2 though, I could see this as well.
I think she's more w9 because she controls her crazy, intense side most of the time and outwardly just wants harmony and acceptance like a 9.
I could see 8w9, 8w7, 2w1, 7w8 , 9w8 or 6w7 (pretty convinced of Sx/So though. she is totally sex drugs and rock n roll)
