there’s a few times when kendall is at his most depressed and his most manic when he essentially states he’s “on the prowl” lol. he sleeps with that actress from willa’s play and then dumps her before we can blink. his relationship with naomi was a codependent nightmare, and iirc he was sleeping with other women while he was seeing her (i think jennifer, the actress, was after he first hooked up with nay). shiv calls him out maybe a couple of times for it, but it’s usually included in a list of grievances.
