In reply to Roc.

I think they should explore his dad as gay and a cross dresser. There is enough footage out there to justify the story without risk of lawsuit. Now as far as Marvin being bisexual they could very lightly hint at it without risk of a lawsuit but any further and his kids will likely sue and likely win due to lack of footage or proof justifying he was really bisexual.
