Maru, Sam, Abigail, Penny, and Alex all give me teenager vibes and that's gonna be a no from me, dog. Though Sebastian still lives at home, he does seem more mature--has a career, can fix up a motorcycle, smokes cigarettes, philosophizes alone in the rain, etc.--than the other candidates who don't live on their own yet so I would keep him in the running to be a spouse (he also reminds me a lot of my real life husband
).
Before someone says, "But Penny has a career," I'm aware of this and I think it's an incredible quality that she has to be able to nurture and educate the children so passionately, but based off her sprite and her social faux pas as you get to know her, she appears quite young and I would never go for someone so impressionable.
Give me all the grown people with baggage, I can fix them; or at least help them shoulder the burden!
