The problem here is having to come up with things ahead of time, when not everything is planned can be a huge complication. When you have Sonia use that spell, you could perhaps have it work like the less GM/DM-taxing divinations of D&D in that you have her make a question that we can answer with a short (usually cryptic) answer, instead of an open ended statement that may or may not become true.

Kinda like, instead of having her ask: "What kinds of dangers lay beyond here?" , which is tricky to reply to, without revealing too much/making stuff up that may or may not come true.

Have her ask: "If I cross this door, there'll be any dangers?" , which is easy to reply with a yes or no, followed by a statement like "Only if thy heart wavers," if need be.

It would work better for both sides that way.
