Can you link it, please? I think you might be talking about the Adam Smith one, which doesn't really say much about his romance. I haven't found any new Rooney ones. It's also worth noting that Adam Smith's job is to overlook the arcs of the entire game, I imagine he's not particularly involved with Astarion. The only things I've seen with Neil is him talking about how he trained his mannerisms to differentiate the two and how he goes from "theatre" to "opera". Plus the thing where he didn't like someone saying they were an Ascended Apologist.
In the meantime, here are the devnote screencaps I was talking about, since they might be interesting to someone: https://imgur.com/a/fwJDUJq
