Wayne manor was extremely quiet... Alfred grumbles nervously and with irritation (obviously to hide his inner anxiety) apologizes for the behavior of the boy, who at that moment was clearly hiding somewhere, not wanting to be seen. Perhaps Bruce was hiding in his bedroom, or perhaps he climbed onto the roof again... Who knows ? In the end, nothing prevents from going inside and finding him...

In addition, he actually ends up in the bedroom. Wayne is lying on the bed, listening to music on headphones and drawing something on paper...
