Cheeky actually still works full time outside of his home. Pretty sure Red did too (though he is no longer with us). Cell I'm not sure about. I'm the only stay at home for sure in our group (but don't do rendering). Something else to consider, even if they were home more... generally unless you have a dedicated rendering machine, you aren't rendering when you are using your pc. Most I know have one high end PC they use for everything, and render at night when it's not in use.
Now that explains why rendering takes so much time. I thought rendering was spread amongst people for when they're not using their PCs (for example at work or socializing somewhere idk). With 1 PC, unless we are talking about a nice Threadripper/Ryzen9 setup along with a Quadro RTX, it can get really tedious.
Anyway, back on the conspiracy theory. I'm almost 99.9% sure Angel isn't Dizzy. Something in her whole story about the older man seems off. That's why i think she is an impostor and works in team with someone. I went back through every Jolina interaction to check for some little, but important detail i may have missed on the other playthroughs, which can help to tie her in the story, but found nothing. So i guess she's either clean or really really careful and smart. If the 2nd is the case, i think her description of the single PC user (40ish, curvy MILF with short hair) might be misleading on purpose. And if that is true, then she's most likely teamed up with Elaine through Bella. Remember that both of them (Bella AND Jolina) were suspiciously eager to jump on MC's disco stick.
P.S
The thing that i'm dying to find out now is how the hell Elaine knew what MC's conditions were even before he got to Monica. Did the father mention this to her on his deathbed? Because it's crystal clear she knew all along what his condition were.
