[OP Manga spoilers] Right, I knew this could happen, haha.
So Shanks and Gaban met when Colon had already been born, so Kanae did know him as a baby, and also, by that time Shanks already had his crew, although we don't see them, it makes sense that Kanae has to be there at that moment, but you know what? It's also the time when Uta was in the crew, so... whatever has to happen, Kanae will be taking care of Uta, maybe she will have a brief conversation between mothers with Ripley <3
