Episode 5:
Need to "damage" the bear could have been easily explained to March: "I do not like what I have to do either. I am disgusted even. It is sad, that the bear has died, but if we just leave it like that, his death will have little meaning. We have a chance to show respect to it in its death by helping others." Or something along those lines. Not that it would change anything that happened after.
BTW, there was an inconsistency in March's ghost form: first she was able to hit her sis, but then she was intangible.
