You should not trust my memory any more than you trust a shady Camonna Tong escort, but I believe he used to initiate an escort quest which led you to a fight somewhere. But currently, as soon as I talk to him the first time, he greets me with the line "I don't know where you're taking us, but this ends here. We shouldn't have trusted you!" [Greeting 1], and attacks me. If you look at the dialogue conditions in the attached screenshot, you might notice that there are only two conditions, taking up slots 2 and 4. This suggests that there used to be more, but they disabled themselves at some point (possibly because the cells were renamed).
