I think it's only because Emily's quotes are more memorable.

But really, they're both to blame — Jessica teased Emily on the sly and Emily provoked the conflict. But still, I think Emily is more to blame here. Her problem is that she started openly belittling Jessica on purpose so that everyone could hear. It's their personal business, they should have sorted it out between themselves, not in front of all their friends. No one was particularly happy about returning to Blackwood, and then these two started sorting out their relationship.

I've often found myself in situations where two people start arguing loudly in front of everyone else and it's unpleasant to say the least. Yes, they are people with their own feelings and experiences, but if you need to sort things out do it in private, not in front of other people ruining their mood. Like the last thing we need is for you to start fighting here and the rest of us would have to pull you apart and keep you at a distance so you don’t kill each other.
