Said no. Saw no reason to lie.
The question is, how the fuck did he know I was lying? We already know that Radiobastard knows Vernon, so was Vernon working with Radiobastard all along, along with information? I think Radiobastard knows I was lying because he took the radio off Clems mum.
I seem to remember Clementine saying something about finding her parents in Vernon's hearing. Im pretty sure thats how he knew.
