[Seem to him like he hit the nail on the head. There were far too many memories swirling around in the puppet's head, so much information that he couldn't get most of it straight in the short time that they were connected. But one thing he did gather from it, which is verified by Wanderer's mere existence here at the bridge, and what he told him when he first arrived is that the person he's waiting here for left a huge hole in his heart that he's never recovered from. It explains a lot to Childe about why his former colleague is the way he is, even if the young Harbinger overall doesn't have much sympathy.
Still, he can still remember those feelings of anguish and loneliness, of a broken heart over the loss of someone important. At the very least, he can empathize with that.]
He was someone worth coming back here for.
[He'll finish that sentence for him, even if that isn't what Wanderer was going to say. He debates for a moment on a thought, but would it really do any good to tell him?]
...Someone worth saving.
[It's almost as if he's asking Wanderer to prove him wrong, like he might know something he hasn't revealed completely.]
