Yes, a great bit of casting with Felix & JJ, resemblance wise (assuming now they are biological Father & Son). As soon as it was announced that James/Felix was joining the cast & pictures emerged, I think the likeness was noticed by most people (& the theory he was JJ's father started straight away).
