Yeah, i think the egg is a distraction, and it's all about the case.
I know this is blasphemy, but i never cared about Carter. Didn't care about her when she was alive, don't care that she's dead. But i wouldn't be surpised if TPTB want to ride on the coattails of Empire's success and try and bring her back for a minute.
And yes, discussing the therapist (Iris? Thanks... ) with Zoe was just...odd.
