Charles Soule’s Darth Vader comic book series takes place right after Revenge of the Sith, so the pain of losing Padme is still fresh.
We’ll have to wait and see if Darth Vader can successfully communicate with Padme in his castle, but I suspect his efforts will be for naught.
Nevertheless, it’s understandable that Vader is so desperate to try to pull this off.
That lingering part of him that’s still Anakin Skywalker would do whatever it takes to see his wife again, even going so far as to build a giant tuning fork castle to get the job done.
