They actually did it, they extended the entirety of that post-fight explanation with Keicho into an entire episode. But to be perfectly fair with you, the photo scene got me pretty hard since these family based tragedies and reconciliations are my weakpoints. But hot damn, they made the Nijimura Bros arc into 3 whole episodes. Thankfully, it seems like Echos/The Lock will be one episode, hopefully it stays the same for Surface.
Special props to the OST for making me feel really sad about the bros.
