Hey, guys, I am totally convinced that Erin is SMART. She is a very calculating person and knows exactly what she is doing.
She really likes Chad and wants him to pick her. Therefore, she is strategically showing Wade that she is not romantically involved with him. Wade will for sure talk to Chad about it and this alone can make Chad feel better regarding Erin's intentions. Now, she is going to tell Chad that after their 24-hours date, she feels deeply for him, everything is clear for her now and she wants to be with him and nobody else. She could not say anything similar to this before the 24-hour date with him simply because they did not spend enough time together and he would not believe her. But now I think he could buy it especially if Wade told him that after the first date with Chad Erin was not comfortable with Wade on their date. Great plan, Erin!
