More of a Fridge Logic issue, but Word of God has stated that sometimes Bruno gets involuntary visions. When this happened while he was hiding, did his door glow for a brief moment like we see in the movie? Did anyone in the family notice and freak out/rejoice thinking he might be back?
Since the doors stop glowing when the power fades/is disabled, Bruno repressing his gift/separating himself from the family meant that he didn't have any visions at all after that point, in much the same way that Isabela wasn't able to use her powers after her door switched off.
