Rengo walks away a short distance with them (far enough for nobody else to be able to hear them). He leans towards them and speaks quietly: "I seriously think we should be very careful with this stranger. I mean, we don't even know her. How do we know we can trust her at all. Don't let her innocence deceive you, is all I'm saying. I'll definitely be on my guard, and I suggest you two be on your guard too." Rengo looked a bit worried.
