First, thanks so much for the kind words!
As for your question: yep, that's a step back from their relationship status. Don't think of it as pushing the issue, and it's not really about the dagger either. It's more so about the fact that X is clearly hiding something incredibly important, which includes severe political ramifications which has caused problems for the Crown on multiple occasions, as well as being emotionally unavailable and distant.
If the Crown just lets it go and makes no further effort to close that emotional gap and hold X accountable, as well as showing X that they want to know the real them and not just the performance they put on, then the relationship remains surface-level. However, it still falls within the acceptable threshold of romance points that keeps the relationship steady, so it's not a problem yet. Hope that gives you some understanding!
