i'm cool with playing it whichever way you want to since she's post-him! i don't know who knows about luke in the hoo universe aside from those who had been in the pjo books, so it doesn't worry me either way. but it'll be cool to see it all play out. jason wasn't told about luke's involvement in the titan war until after they shared a friendship necklace. it's nice to see it happen again, but with someone less dumb than him ...
