In the aftermath of the kidnapping incident and Ren's able handling of the matter, Ren soon became hot property in Sand Country as well as Dune Country. The minister personally appeared at Ren's apartment the same evening to enquire about his well being (and to filch a scrumptious dinner, but no one would mention that, naturally).
Little Brother Wade had insisted on coming over to Ren's apartment. The Blue Wolf member who was supposed to take him back was caught in a dilemma, and ultimately called Fang to ask what to do.
Fang generously decided that he may as well let Ren and Wade reconcile. After all, Wade had been making great efforts to make amends, and Fang's gut feeling was that Wade really did care about his Big Brother.
So Fang asked Wolf's subordinate to bring Wade to Fang first and then the two of them could go home together.
