Here’s the awful secret that “Truth Tortoise” told Morty in last week’s episode

Every episode of Rick And Morty is full of wildly divergent adventures into fully realized sci-fi premises, but last week’s episode, which functioned as this season’s clip show, had more than most. It started with a truly intense segment, in which the titular duo found themselves being chased (or accompanied by?) some sort of Sandman clone through an Escher-esque dreamscape. Morty was gripping a “truth tortoise,” who somehow psychically conveyed a truth to him so horrible that it led him to yearn for the memory itself to be erased, thus rewiring the very fabric of his perceived reality and leading to a full-episode exploration of memories too painful to bear.
