It is also a grey area. I mean, it is a bit not "fair" to Troy. It is a sort of betrayal. I am not sure, does this mean, I have got my word or not? I think it mostly does.
If someone called, "A", introduces me to "B" and "C".
Then I fall out with "A",
(i) I will either elect to end relations with "B" out of respect to "A" if I choose to fall out of them; and
(ii) I will still end relations with "C" if they fall out with me or request.
If there is any business, I will cancel or quickly finish or transfer to another party of their choosing.
