I suspect that the "young girl" in the locket is no longer a child but an adult (considering the photo is aged). Likely related to your situation, maybe even your aunt... making your grandmother the one who betrayed you (unknowing thinking you and your twin died with your parents)! You probably then are told to keep the locket so it then becomes the desk item.

But, honestly, I think I'd love it if it turns out that it is the follower you convince to help you (or not)... In which case if you do (not sure the other path), you are the cause of her demise without even knowing it.
