ellie was walking with gabby & tess in the forest, it seemed they were all bonding and you needed an alliance, so you went over to them and introduced yourself.

Tess : "We do need more people in our alliance after Lake got voted off, Would do you say girls?"

Ellie : "Sure, they seem nice. Welcome to our alliance!"

the only person you really knew was Ellie since you both went on season 1 together, she smiled at you and you smiled back.
