Jason has memorized the time of night where Dami usually gets nightmares about dying and so every night at that time he'll walk past Damian's door (to see if he hears sobbing or not) when he here's sobbing he'll walk in and carry Dami while walking back and forth while singing Evermore from "Beauty And the Beast(2017)". Dami never says this but he honestly loves to know his brother cares.
