what does he mean "Wait and see" in reference to Leo and Calypso meeting up with Jason and Piper?

I actually think that Nakamura liking Luke sounds pretty cool, it adds to the plot more than Nico's coming out did anyway. If you think about it, they both had to leave camp because they didn't belong and it later turned out that Nico did that because he was gay. It would also have his in the same sort of character development as Annabeth, getting used to Luke being Cronus. I've never considered this before but it certainly adds a bit more depth!

Finally, I just checked RR's blog and he mentions Lord Nelson as having a cameo appearence in the Sword of Summer, thoughts?
