After listening to what Molly told her, Quinn's mind started to rumble with so many scared thoughts. She forgot how to think straight and the one thing she knew right now is that she urgently needs Eve's and Rachel's help.
They promised to be on the lookout for Wren but Eve looks so distracted with the conversation she's having with her mom. Wren could just slip past her and she wouldn't even have any idea. Rachel's busy with Simon as always.
Rachel can't provide more help to her right now the way Eve can, she and Eve have always been the one to come up with solutions to different kinds of problems they used to have. Rachel was more like the baby type, she gets scared easily and then runs off when she can't take it anymore.
So Quinn had to turn to Eve right now. Their mindset kind of works together in the same way sometimes. If Wren shows up here tonight like Molly threatened her that she would, then it's definitely over for Quinn.
