Darren sued over a HIPPA violation. The HIPPA rules are fairly specific, and no one from AIM should ever have spoken his name other than to talent etc (whatever the AIM testing form allows). AIM may have thought that once the talent blabbed Darren's name the cat was out of the bag and they could discuss it, but that's not the way HIPPA works.

The girls might have had a HIPPA case against AIM but did not pursue it for whatever reason. They could have sued Darren obviously since he had an extra $100k in his pocket.

Split That Booty 2 was released without any of the Darren/HIV scenes: Lara's scene was removed, not just her name.

Lara was rumored to be hooking even before the HIV thing, supposedly a little extra for bareback. And one look at her and you wonder about smack, needles, etc... She was a risk factor waiting to happen
