Another point to consider is that the SI's perspective on how people are reacting to them may be wrong.
In This Was Easier on the Tabletop, the SI gets on fairly well with Katrina Steiner - or so he thinks. Yet it turns out she was deeply resentful of him saying such unpleasant things about the future on his family, and he only learns this when she sends a written apology after learning of him risking his life to avert those events.
The SI knows what characters did in the source material. That's not the same as knowing them as people. They should be more complicated than they seem at first glance.
