I didn't really consider that she could join the crew when she showed up. I just saw her as a confinient way for the SH to get info on mermaid island and especially how to get there.
Whether she joins later, I don't really care atm. Would certainly be funny given her attitude. But on the other hand she can't even walk. She seems far away from being 30 (at which time the tail turns into legs), so the SH would've to carry her around all the time. That just doesn't seem likely to me.
For now I'm curious about mermaid island. Is it under water, how will that affect the DF users. If it is in a bubble at the bottom of the sea, how do all the mermaids move around on the "dry land" with their tail?
Knowing Oda it'll be sweet.
But I'm also shocked, how easy Ruffy decided to do nothing about the Ace thing.
