We do know the identity of one of the persons by which this dilution is being achieved, that of course being RP. Could it be that since Urbach is new, she has not yet been bitten?

Certainly, she is not displaying the "Once Bitten Twice Shy" perspective.

and appears to be actually turning the other cheek or so it only seems that that is the case?

I wonder how SK thinks about all of this? What is his take on RP, BP and JL and the apparent nonchalant attitude towards 13d? He speaks so quickly and pressed. I'd like to know what he thinks.
