Many. But we are not allowed to sleuth outside of POI or Gabby so I must behave myself. I have said before that Gabby being involved in at least the Bumble app instantly makes her a target for predators. The vanlife is also rife with some creeps along the way, easy to get caught up with during camp times....my own personal experience here as a hard core introvert, still ended up in, well, interesting situations and groups.
I don't believe she was left alone when Brian went home for the "storage" trip. So who was there as "acting as a support system"? And no, it wasn't just her dad on video call for 5 days. No way. So who? We don't know and can't sleuth publicly here outside the guidelines.

All weird, stays weird...we just don't have enough pieces. And maybe we shouldn't. Cassie said, the world does NOT need to know what the FBI knows. Why? Who is being protected by the FBI or by not releasing some additional information? I can guess. It isn't Brian or his family, they have been beaten every which way and sideways. Maybe rightfully so, maybe not. I do NOT know. Thank you for asking me. Sigh.
All of this is my crazy opinion ONLY!
