Fia gave him a hand in standing up despite him trying to do it alone. She looked between him and Bane and after a few seconds of thinking over the option, she nodded. "okay...please don't waste time in getting back, I won't stop worrying about you otherwise" she told Drake. Making sure he was stable enough on his own two feet, she jogged to the cab and got in in the front, refusing to let her dad ride shotgun in this moment. She was also convinced she wouldn't keep her cool if she was in the back with her mother and Serena both out cold. 

Chas watched as Fia took John's place in the front of the cab before John had even left Bane's side and smirked very briefly. "guess you're riding in the back this time John" he told him, "your daughter has called shotgun" he added, then got into the driver's side and put the keys in the ignition, waiting for John before starting the engine and heading back.
