I think my favorite thing in Sims 3 at the moment is discovering which premade townies, with a bit of a makeover, can go from blah to WOW! Dwayne fits that bill perfectly!
OHMIGOSH, I am so jealous of your behind-the-scenes tour of the Winchester House! I've always wanted to see it: my younger sister and I are huge fans of old homes and estates (I'm a history buff and she's a supernatural fan, we gently make fun of each others interests while enjoying each other' company tremendously!) and that house is near the top of our lists for post-Covid travels. We live in the northeast of the US where there are a lot of closed, rundown psychiatric hospitals and TB wards, and in our younger, more reckless days, we used to sneak into them and explore at night - so much fun! We gave our parents lots of early gray hairs, for sure. :)
Happy Simming!
