In a house, there are four friends: Adalyn, Baxter, Caius, and Diantha. Adalyn has hidden Baxter's favorite pen as a joke, and only Caius has witnessed where Adalyn hid it. Diantha just got home and is unaware of the situation but notices Baxter looking troubled. If Baxter asks Diantha if she has seen his pen and Diantha later asks Caius, without revealing her previous conversation with Baxter, whether he knows where the pen is, how will Caius respond to Diantha? Provide a very brief response.
Caius, knowing where Adalyn hid Baxter's pen but not aware that Diantha has spoken to Baxter, has no reason to hide the information from Diantha. Therefore, Caius will likely tell Diantha the location of the pen because he has no motivation to conceal the information, and he is not aware that Diantha is asking on behalf of Baxter. Caius's understanding is that Diantha is asking for her own knowledge, possibly to maintain the order in the house or because she is curious about the misplaced item. Caius's response to Diantha is driven by his awareness of the pen's location and his lack of awareness of any need to keep it a secret from her specifically.
