Zach does not like this one bit, but when Aaron gets into the car, there's no way Zach is going to leave him there alone, so he follows. Once Akins has closed the door behind Zach, he reaches over, trying to subtly take Aaron's hand to hold it for comfort and support, hopefully without Akins noticing.
He waits until Akins is driving, then gets out his phone and, hiding it by his legs so the sheriff hopefully won't see, types out a quick message to Emily.
Zach: | Akins arrested me. No idea why. Really fishy. Says he's driving me to station |
