After getting the reward for the quests in the Adventurers' Guild, Diana and I leave, but on the way out we pass Prince Drago de Cartoza.
I was startled when I saw him but forced myself to keep an expressionless face, I also warned Diana about our connection to her being my Familiar to act like she doesn't know who he is.
After we left the Guild Diana and I walked back to the mansion while we talked.
"What was he doing there? And why didn't he stop staring at me?" (I)
"Do you think maybe he recognized you?" (Diana)
"I don't know, he looked surprised but also confused, I don't think he can recognize me as I don't think I left any kind of lead for him to follow." (I)
"Maybe he asked Carlos for some information or maybe his reason for coming here is something different." (Diana)
