The only stop that is common to 65 and 80 is Vivocity as at
Macpherson they cross each other but don't have a common stop.
Services at Vivocity
10, 30, 57, 100, 131, 143, 145, 166, 855.
Only 100 is HGDEP. But B cannot be 100 as it meets 147 again at
Commonwealth. Is your question incorrect?
So sorry I confused u - B met C in somewhere along B's route and
D in another segment of B's route.
