Ah! We see. Is the "tiny computer" labeled PreFab?
The Father is Looking for his Son (labeled Son). Try looking for him in the BitCoin Mine (the yellow cat can give you direction to the Mine).
Good on you for finding them, they are both secretes for a better score. Also the PreFab, is a secret for another character.
If the characters are repeating themselves they most likely want something else.
Some characters do have additional dialog after being given what they are looking for.
Again, Thanks for the feedback! :)
