I think she said a skinny rapper with tatoos. And yes he she said to Karly that she thought he was hot. BUt what happened was master manipulator Sree, had a talk with them, and he mentioned how he thought Cairon was nice but immature, so thats why he (Sree) gets along with the girls more
After that, Sophie felt kind of uncomfortable, and told Karly maybe he is too young!
