For most people, a stranger being recognized in a friendly manner would make a person less tense. It means that this person is not an enemy, that they are familiar in some way or another.
As it has been stated before and likely will be again, Savio is not most people.
Taking in the information with careful consideration, the Antivan considers the information, but it is not long before someone else gets wind of the conversation. Narrowing his eyes as he looks back to Hilda, the killer gives a frustrated sigh to the fellow elf in the shadows. "Go, it looks like you have a someone wanting to talk with you... Raelias. I am sure that they may be willing to answer some of your questions. I hope for your sake I do not find anyone else skirting about."
Calling out to the camp, Savio replies, "Your 'friend' is here, my tall bastion of beauty." At least he manages the given title to Hilda without sarcasm in his current state.
While Savio waits to see if the elf continues on, for the time being, the Crow does not follow. Why? Because assuming that the Orlesian traveler enters the camp, the assassin will preform a couple more patrols in silent around the area, taking seemingly annoyed bites of pastry as he goes. Trust issues with a Crow? Say it isn't so.
