"You killed that guy's girlfriend?!" said Summer.
"She was a poorly written character who would've made for a terrible romantic partner for him. Also, I DID cure his blindness, so you're welcome." said Rick.
"Grandpa Rick, what you did wasn't only inhumane, it was misogynistic as well!" said Summer, "There's a name for when a female love interest is killed off in a movie; it's called 'Woman in the Refrigerator'!"
"Yeah, nobody gives a shit about your Tumblr educated feminist talking points, Summer." said Rick, "You wanna talk about problematic? You fetishized someone who was previously handicapped."
"All I said was that I thought he was cute. I didn't know anything about his backstory until you told me." said Summer.
"Rick, she DOES make a good point about you killing Kayley. What you did was pretty cruel, whether or not you were drunk or if she was a poorly written character." said Morty, "I know we don't time travel, but I recommend you try to fix the problems you caused."
"Ugh. Fine. If it'll make both of you shut the fuck up."
Rick took out his portal gun, shot it at the wall, and went through the portal where Garrett was mourning at Kayley's grave.
"Yeah, hey, about that whole 'Killing your girlfriend and making you have character development because of it' thing, I realized it's a tired cliche that needs to be put to rest before it bores everyone and has film makers receiving hate-mail because of it. So here."
Rick pulled a new Kayley from the portal.
"This Kayley has the same memories as your Kayley and her Garrett got killed by Ruber in her dimension."
Garrett looked at Kayley, and she looked back. The both smiled and hugged one another.
"You know I'm not forgiving you for killing my original Kayley." said Garrett.
"Didn't think you would." said Rick before turning to Kayley, "Kayley, two words: Knight Training. Work on it if you wanna be at the round table. Okay, bye. Wubba-lubba... whatever."
Rick then went through the portal back to his dimension.
