I’m pretty sure Chloe found out it was Nicole. And they becomng BFFs is probably something the writers just decided to toss in. How else could Nicole come up with a buddy after all she’s done in the past. By far not on a par to Sami but I think Nicole’s ‘sins’ were much more severe than Sami’s. She’d have to get forgiveness from whomever they decided to pair her up with.
I always liked the sisterhood between Jen, Hope, and…who was the other one, Kayla? It’s so cold here, I think my brain has frozen. I remember a scene where they were all sitting on the couch, eating ice cream out of the container and commisurating with each other.
