The scenes between the Archbishop and Frank were ludicrous. And pointless.
Re the Erin/Eddie thing-- it was all backwards: I have learned after watching every single episode of Law & Order: SVU (and still watching -- you can get CEUs for that, right? 😉) that it's the police's job to dig up enough evidence to make a case, not the DA's. Olivia Benson would have investigated the rape situation from the cop side, found the other women, and brought all of THAT to Erin, ready to go. She would not have expected Erin to do the legwork. Eddie should have gone to Jamie or Danny and asked THEM to investigate. Even though Eddie was out of line, that threat by Erin at the end was bitchy-to-the-max and way over the top! "Make you wish you'd never been born"??? WTF?
