Kayla's sister is never called Emma Frost in the film, if she was Kayla's sister she would be Emma Silverfox. It is down to the writer/director and the characters they wanted to use. The Emma in X-Men Origins: Wolverine only showed the diamond skin, where as Emma Frost is known to be a powerful telepath which was shown in First Class. The First Class Emma Frost was Emma Frost where as the X-Men Origins: Wolverine Emma was based loosely on Emma Frost.
