User blog comment:IamThorn/Nora v.Ren & Yang v.Ruby/@comment-25091485-20140923121259

The only time I think Yang could possibly hurt Ruby would be when she is in her 'Beserk' mode and it would likely be an accident of some sorts. (mistook Ruby for someone, etc)

Nora? Maybe in a playful sort of way but it wouldn't really classify as 'hurt'

Honestly, i seriously doubt they would actually fight and even if they hurt each other it would be because of a mistake / accident.
