I figured Jessica would stop Trish, but I wondered from the beginning if a half-measure was at all helpful. I think, at the end, that was proven right as it all fell apart. I can't entirely blame Trish for her actions, but they certainly were counterproductive. I love the reference to the fact that Salinger was mauled (like a cat). But it sucks that Costa took the fall and, as I said, I don't think it contributed anything.
Things are definitely picking up towards the end. That alone will improve it over last season, which fell off a cliff around episode seven. Four and a Half Stars.
