Jesus keeps his hand on K's, resting it there, not wanting to lose contact with him while K seems so distant.

"And they hid the child in the orphanage when she died." He's following all of this so far. But the underside of it he doesn't understand yet. "Everyone thought you'd killed him. The 'child'. But you were still following leads no one else would have found."

He needs, in some way, to hear it: the thing every other orphan he's known, the orphan he's been, has wanted. To find their parent. To go home.
