Gotta say, I really liked episode 3. Even though everybody knew Pickle Rick was coming, the reason for it and the pickle-related shenanigans were pretty damn funny. His exchange with the therapist was solid, and I think on some level made him reflect on his actions a little - at least enough to fake being remorseful to Beth and ask her to go get a drink with him even while ignoring the shit outta the kids.
This episode also showed that in a lot of ways, Beth has a Rick streak of her own, and in large part because of her relationship with him she thinks that therapy and being ordered to do shit is meaningless, even though her children are crying the fuck out for help that they need after the shit they've seen. It makes you wonder the depth of Beth's knowledge of Rick's adventures and how traumatizing they can really be; presumably, not a whole lot.
