the new legacy sequel
Going to call it now. Julie/Ray/we will be made to think it's Ben Willis again. And Will won't be mentioned at all. But it will be Ben's grandson, born by his daughter just before her death. Conveniently never mentioned before, but also never specifically said they didn't exist either, so it could work. Also explaining Ben's hatred for David. He'd be late 20s, early 30s, depending when it comes out. He grew up bouncing around the foster system. Learns his family's past. Blames Julie and Ray for taking away his family and growing up that way.
And I hope Brandy comes back too. But could end up being a glorified cameo with a cool death scene.
