Delta's face changed from sadness to a worried look.
Delta(with dismay voice): His condition?
Shin just nodded her head in agreement.
Delta: What happened?
Shin(with fake sorrow on her face): Yes, it's just... mmm... his condition is worsening day by day.
Delta: But you've fixed him yesterday right?
Shin: Yes, I thought everything was fine, but when I was just going through his day today I found that a chip in his motherboard is damaged.
Delta: We can find that chip and replace it right?
Shin kneeled to match the height of Delta and made eye contact with him.
Shin: The manufacturing of that chip was stopped in the early '40s, we can't replace it.
Delta: We can bring his memory back into another robot?
Shin: It's a complicated process, his version is really old, I can't guarantee it. Even if we do it he will be a robot with no emotions and his memory of emotions may get lost forever.
