Final answer:
Jayson might believe Ariana Buckmiere is going to be surprised because he knows something she doesn't. This often happens in narratives where one character is aware of something the other is not. Context is needed for a more accurate interpretation.
Step-by-step explanation:
Without context, it's difficult to definitively explain why Jayson might believe Ariana Buckmiere is going to be surprised. However, this type of statement commonly appears in literary narratives. Perhaps Jayson knows something that Ariana does not, leading him to predict her surprise when she discovers it. An example could be Jayson planning a surprise birthday party for Ariana- he knows about the party, but she does not, therefore he anticipates her surprised reaction when she discovers it.
A thorough understanding of Jayson's perspective, Ariana's personality and situation, and the context surrounding this statement is necessary to form a more accurate interpretation.
