If Rayleigh stays on AL, then the crew will end up meeting there. That's very likely since Luffy promised all the girls that they'll meet his crew. Also, the interraction between Hancock and Robin & Nami can happen sooner rather than later.
Why is everyone saying this? the vivre card doesn't point to the person, it points to wherever the other half of the paper is. Rayleigh said that he gave the vivre card to Shakky, so as of now the Straw hats are still headed to SA.
