Thanks! I had never written this pairing before, so it was a test for me to come up with my own characterizations.
bk7brokemybrain helped me stay true to canon (she is my lovely canon geek).
I so wanted them to make other choices and not have canon happen at all to poor Harry, but, then again, I think if James had raised Harry (with Sirius alongside), Harry probably would have been an entitled bully like those two.
