"We follow. At a short distance, but never out of sight."

As far as Inessa's concerned, Ophelia will be fine and anyone attempting to change that will come to regret it. (However, she did slip an amulet to her earlier as a form of insurance, just in case.) She nods for Ophelia to respond, quiet assurance in her stance as she's reminded her fellow Fereldan that they will keep her in view at all times. From earlier conversation with Ophelia, though, the Grey Warden has mentioned that the less the Valet sees, the better. If they have no time to enter, that will work in their favor. Otherwise, they can be merely 'saying their farewells' and follow along from that point.
