Jen Mccabe trial rewatch

I’m just at the beginning of her direct, something that jumped out at me was that she says Brian Albert Jr was supposed to come out to have drinks for his bday, but didn’t end up coming out bc he suffers from really bad anxiety and it was bad at that time. So why is his father inviting everyone and their mother back to the house to celebrate with them? I can’t figure out why they would have to lie about being at the Waterfall and then going back to the house - why not simply say ‘we’re going back to the house to continue the party if anyone wants to come’.

Also, she repeats the story that Karen was the one who wanted to go for pizza, I think Chris or Julie were the ones who introduced that story, I guess the reason to make a point that Karen really wanted to continue the party is that the only reason she didn’t come inside is because she hit John in an angry rage? Her direct seems SO scripted I just can’t.
