Ya there would definitely have been a reason like maybe Kira had to become old enough to learn about the supernatural just like how Allison was brought into the family business only once she became 17 in season 1 so the not telling her thing isn't really a bad thing but she should have explained it once she realized that Kira had learnt about the supernatural.

and for "a)" I honestly don't blame her (though it was really stupid) cuz her people would not have died if not for that greedy doctor so you could say it was his fault that caused the nogitsune's summoning.
