Another thing that I like about this show is that it shows not only what to do, but what not to do. For example, when you have a wingman always get your stories straight before entering in a set. Women are not dumb and will pick up any incongruences in your stories.
You are right Matador was not listening to JD. The hb pick that up right away.
However, if JD set was truly strong then the hb would not have continue talking with Pradeep.
Her IOI would have been acknowleging Pradeep and including JD in the conversation with Pradeep.
This was a definite IOD for JD.
