Something just occurred to me. What if Lana didn't die from drugs, but from AIDS. She contracted HIV with a dirty needle and then AIDS broke out. That could also be the reason why Lana had to leave so as not to endanger Jill.
strange would have it, the HIV virus has its origin in the SIV virus, which comes from different monkey species.
What if Lynette also had HIV. If the HIV virus is detected in the mother at an early stage of pregnancy, medication can be used to prevent the virus from infecting the baby.
The question that now arises is how Lynette could have contracted it? Neil. Neil, as we learn in EP8, probably fucked another woman a year before Lynette. With or without a condom? What if Neil contracted HIV there and passed that on to Lynette. No wonder if Lynette's parents didn't want to have anything more to do with Neil. That could also explain Neil's fixation on condoms and why he didn't let another woman into his life.
However, the MC does not have HIV because the onset of the disease without medication is between a few months and 15 years. That is why the MC's beating at age 15 was so dangerous. If it was known so that Lynette had HIV, but the MC was never tested, the brawl was the pivotal event where it was determined that the MC was not infected. Why?
He hit the guy so hard that the hands bled from the MC. Ergo, the blood from the MC was on the guy. It was then waived from the charge because it was determined so that the MC was not infected with HIV.
But now it is so that Lynette is connected to the Royce in some way. Let's call it family friendship. But by this Jill knows so that Lynette has had AIDS and wants the STD test.
