This may be a bit pedantic, but isn’t the A->C relationship wholly contained in the A->B and B->C relationship? In other words, the only way A->C works is via B; there is no “extra” information in the A->C relationship.
A good deal of A → C goes through B, but not all. Affect can directly influence things like heartbeat and other physical conditions, which I’ve classified under C, without going through voluntary action, which is B.
