Huh. Interesting. Lydia is kinda like that too, except she's trying to prove Mario is innocent (in my version, it wasn't Mario who killed Morton, but Tatanga in disguise), and she got banished for "treason". I haven't decided on where she's hiding out in specifically, but it's somewhere far away from the Koopa Kingdom. She's basically like Homer's mother Mona from the Simpsons, where she's on the run from the law. She does want to return to her family someday, especially her kids, but until Mario's innocence is proven, she can't go back (lol, it's an SU pun).
Really? That's interesting to hear. What happened to Rose?
In my version of their backstory, Morton had three wives, Annabelle (Ludwig's mom), Karen (Roy, Wendy, and Morton Jr.'s mom), and Lydia (Lemmy, Iggy, and Larry's mom), and Bowser Jr.'s mom is Clawdia (Bowser's ex-wife), and he also has a little sister named Anya (who is currently living with Clawdia).
What happened to the moms, you ask? Well, Annabelle is dead, Morton divorced Karen because she's... well... a karen, and Lydia ran away after her husband died.
