I remember a while back seeing this article somewhere about a tweet some guy wrote about doing a date scene that day with Portman. So I think maybe she's not just burying herself in work but actually trying to move on. And I doubt they'd start with Thor already there too. Him coming back to Jane would be an important plot point considering where the last one left off, they wouldn't not show that.
