What is your sims deepest or darkest secret?

Well, my main sim, Hal, is actually a very old grand master vampire, so there's that. He used to be infamous in the vampire world, feared even by his own kind, and second in command only to the last remaining original vampire. He's spilled more plasma than anyone. However, he has a dissociative identity, i.e. his personality is split in two, and Hal is the half that wants to be a 'good vampire' and live as human a life as possible. So, everyone else is safe for now and just think he's this young, harmless, gentlemanly, adorkable stay-at-home dad. Just don't stress him out or Harry might come out to wreak havoc. Grim wouldn't mind so much. He seems to be one of Harry's biggest fans and even asked for his autograph after he gave some poor chap a cardiac explosion. :D

The only other secrets I can think of aren't quite so big or supernatural, but still dark in their reality. My sim, Rhys aka Bunny, is a total sweetheart but secretly suffers with depression, while his goofball bestie, Dave, has an enthusiasm for juice that's far worse than he's willing to admit, even to himself. Dave's also been completely in love with Bunny since they were kids, but doesn't feel good enough for him and pretended he was so drunk he actually forgot the one night they shared together. Thankfully though I do plan for them to confront these issues and have their happy ending. I guess I'm just a big softie at heart.
