Princess Carolyn burried Tim Burton and covered his death.
In S04E04, she says to Ralph “so the studio finished Mars Attack without him. And since they never found the body, my client Tony Trombonni has been making movies under the name Tim Burton ever since”. So we know that the real Tim Burton is dead and that PC know, but where it gets interesting is when you add S03E03 : when Mr. Peanutbutter tells her “I need your help, I’ve done something bad, very bad !” (he got skunked), she answers with “Put the corpse on ice, I’m on my way”. So obviously she’s already helped cover a murder, and seems very chill and pragmatic about it.
I think the reason she knows how to deal with a dead body is because she helped a client (possibly Tony Trombonni) cover the accidental or voluntary death of Tim Burton, burried the corpse herself in a place where it couldn’t been found, like a desert, and then kept covering the tracks.
I think it’s perfectly in character for her to help with a murder because she just can’t say no to people.
What’s the 'name of Bojack’s grandfather ?
