How impatient! But honestly, Strange can't blame Billie. The moment he started this research, he was also thinking of ways that he could use it.

"I think the best thing to start with is a newer item. That way, it's got less history to work with. What we'll do is take the item in our hands and draw upon the world's inherent magic in order to view the item's history—or at least, know it. I don't think we'll physically see the history, we'll just mentally know it."

But they won't know until they try. And Strange is doing a poor job of hiding his excitement as he thinks about the possibilities of empathic magic.
