X-23's Foot Claws Shown in Recent Promo for LOGAN

X-23 showed her foot claws in an over the weekend promo for Logan! In the comics, those feet claws have come in handy more than a couple times for the mutant, so I'm sure we'll see her put them to good use here as well. 

So, I know this is a movie and all that, but how is Logan going to explain how an adamantium infused mutant is able to continue to develop and grow into an adult when her bones are stunted inside the metal? Maybe I'm reading too much into things, but now that I've thought about it it's going to bug me if X-23 turns into an adult mutant down the road. Logan opens this Friday!
