After the call with Nathan, Caily became restless and worried about him. Although it was mildly saddening and at the same time terrifying to hear that Mirabel had died, all of her thoughts and worries were on Nathan's situation—He was being framed for her death!
Caily's restlessness continued to radiate from her until they arrived at the estate.
Immediately Alex pulled up to her driveway in front of her house, Caily didn't waste a second to jump out of the car and went straight to the backseat to Toby and Ruby to help them out of the car.
"What's wrong? Why are you in such a hurry?" Alex wondered, opening the side of the door where Ruby was and getting her out of the car.
At the time Nathan called, Caily's phone was off speaker, so Alex couldn't overhear the things Nathan had disclosed to her. And now it all made sense to Caily why she hadn't seen Mirabel for days.
