Just finished it. I confess that I didn’t see the JJVerse reference.
Maybe the drones scene as well; similar to the ones in Beyond.
I made it to the section with the drones and initially thought maybe that was it as well. But then I thought that wasn't really an Abrams reference. I mean, it had a similar feel to an extent but that was all and I thought if James mentioned there was a reference it'd probably be something more overt then that.
I'm still looking for it. I'm about 3/4 of the way through now and keeping my eyes open for it.
When I saw the Dimorus reference I remembered hearing that name before and thought maybe that was it. I looked it up in Memory Alpha and found it was familiar, but because of being mentioned in WNMHGB.
He did give us a small clue, that being the reference is in the 2nd half of the book.
