I think Emma was also weirded out by the situation. She was running on adrenalin before to save Henry, and now it’s worn off and the sheer weirdness of her situation is hitting her full force. A woman she thought was just her roomate/friend and the married man her roomate was having an affair with are now her parents and wanting to hug her and BE her parents and oh by the way, they’re the same age as her or younger. Huh.
