Warning: Full spoilers for the episode below.
Penned by Gotham star Ben McKenzie, who's previously stepped behind the camera to direct an episode, "The Demon's Head" felt like a run-of-the-mill chase episode for the series (someone's being hunted, Jim has to find someone, etc) with the exception that Ra's al Ghul was the one doing the chasing (or, his dog-man Anubis was at least) and the outcome seemed to hold serious consequences for Bruce.
Admittedly, as soon as I saw that the story pivoted around the fate and well-being of a young boy (in this case, Benjamin Stockham's Alex), I expected the worse. But not only did Alex help us see just how much Bruce had changed and hardened, for a teen his age, compared to his peers, but we also heard from Alex what all the other kids think of him. That he's some sort of reclusive "weirdly cool" Howard Hughes-type who just holes up in his mansion all day and ditches school. Yes, the fact that Bruce doesn't go to school got a nice shout-out.
