Vrenille sits back in his chair, his expression mild as he gives a small shrug. "Okay, so y'do." He's certainly not in a position to tell Ed what he does or doesn't know through his own experiences.

But more to the point, it seems to him that he's being told to back off, and he can accept that. There's a fine line between offering and pressing.

So, no pressure. In fact he just leaves a moment of quiet, gives Ed a chance to change the subject to something that suits him. Or else to fill the silence by saying more about this subject, should he find himself feeling the need to get a further word in.
