X-Men: Rogue Questions

His mutation had adapted to the metallic claws to the point that, in order to house them safely in the body, he'd developed a bony underskeleton for them which wasn't revealed until the metal was gone. (This is biologically sound. Even the normal human body will react in strange ways to foreign objects which are housed within for extended periods. Normally, myelin protein surrounds the object but doctors have found bizarre exceptions. Bone isn't out of the question.)

As these claws are a direct product of Wolverine's mutant ability, it is entirely conceivable that Rogue could duplicate them if the conditions were right. Spontaneous bone claws, however, are a bit of a deus ex machina.

It was however later retconned in Origins that Logan/James Howlett/Hugh Jackman/whoever had the bone claws the whole time. That is they didn't develop after the bonding process, rather the adamantium was bonded over already existing bone claws.

But again, it is Wolverine. Nothing is 100% certain. All the memory implants, retconning, and lack of a defined origin for a writer to adhere too has left us with a whole lot of information to sift through.

Jam it back in, in the dark.
