What I love about the whole bone claws situation is that it plays thematically into the film big time. But, if you discount Origins Wolverine and just use the flashbacks from X-Men and X2 as the official backstory of Logan, seeing the bone claws for the first time in this film is really interesting. It doesn't feel out of place.
I know it technically ties into Origins Wolverine but because that's the only thing they reference from that movie, I think it plays as a nice revelation for people who haven't seen that film or who just discount it....like me.
Yes, they just show them, no big deal.
