Jabba, you’re such a negative Nelly. Maybe they had a family emergency, and they had to leave right away. Possibly, a beloved family member had a heart attack and in order to see them one last time, they had to leave immediately, and they knew they might not be back for a while.
Your idea is also possible, but you just jump to the most negative possibility. It was the same with Kira & Nina. As soon as it was known they might stay on the project after the baby was born, you said it was, “…the most stupid idea,” when in fact, it’s already being done by at least three past participants/managers.
As I said, your idea is also possible, but you know how mistakes are made around here. It’s not like the wrong reason for absences hasn’t been listed before.
Now, you know Anna & Alex still visit, as do Scott & Stephanie. IDK about Stifler. I don’t always see everything that gets posted, but I’m sure he’s still connected to the project, as he installed the cams, and was doing so right up until the baby came.
