Personally i love the episodes with more character developement better than the ones that are filled with action (even though I love both) so this one did the Trick for me. For all the people complaining about ,the tragic Rick' is an easy fallback for the writers, I couldn't disagree more. I just love how the show slowly shifts from rick being an genuis asshole who still get's adored and admired by all the other characters to him being alone because of his behaviour. All that around a simple toilet was genuis.
