In water, your initiated turning points are acts of vulnerability. You change your life by admitting something — the feeling, the need, the truth you had been protecting everyone from. It costs you disproportionately and it moves things nothing else moves. Your bravest decisions will look, from the outside, like a moment of weakness.

In Cancer this point remembers. Anti-Vertex attaches chosen turning points and the moments you moved first to people, houses, smells, and specific years, and nothing in that archive ever gets marked as resolved. You scan every room for whether you are safe and whether you are wanted, in that order, before you have consciously decided anything. Old hurts here do not fade — they quietly steer choices you are certain were logical.
