** After suffering from horrible nightmares, Ruby falls asleep on the Slayer's shoulder, and he lets her. It really shows how much trust they have in each other.

* The Doom Slayer and Ruby's growing friendship throughout their struggles together. As hard as he tries not to get attached, the Slayer finds himself growing to care for her and her team, in his own gruff way.

* The Broken-Horned Baron actually mourns its then recently killed bond sibling and becomes enraged at the Slayer and Team RWBY. It's a small moment, but it does show that even ''demons'' are capable of developing some modicum of attachment and even care for those they surround themselves with.
