Like Father, Like Daughter
There is so much going on in every episode of Rick and Morty, and never a dull moment, we sometimes fail to notice the little things. For example, that Morty is the only member of the Smith-Sanchez family with distinct features (his round face), or the fact that Jerry and Summer look exactly alike.
Summer is basically Jerry with different hair and different clothes. Rick and Beth have similar features, but they aren’t the same person. Luckily for Summer, she only resembles her father physically. In character, she takes after her mother. We don’t know whether this was just laziness, or whether there’s a deeper meaning behind this. Either way, food for thought.
