Watching Jacob go off to get drinks she decided to work on Summer, lowering her voice. "Ok I'm being mean but... come on! I know you both like each other. Pleeeease tell this is going somewhere? You're good for him!" She put on puppy dog eyes, trying to make Summer say something about it, anything, before Jacob got back and she could pounce on him.
