Jack recognized the boy in the brief memory, but not the house, and he knew it must be where Gus was living before Wren got him back, with the people who had abused him. He didn't know the woman who had been caring for him, but it was a comfort to know someone had cared about him, even there. Or it would have been, if anything was making it very far beneath the surface. When he would think back on it later, he would be grateful.
