During his recent interview with Hugh Jackman, which you can see here, Wolvie himself indicates that he’ll tell Ninja a few things about Wolverine off camera. Here is some of the off-camera scooping.
Apparently, Dom’s part in the movie is larger than what people were estimating. There is speculation he may even be Wolverine’s side-kick in the movie.
As for his name, originally he was called ‘Beak’, but due to some copyright issues he has been renamed! The new name is either Blackwing or Blackpool. As Ninja says, “Blackpool fits well, if they keep his accent.”
