Juror #9, an elderly man, was the first to change his vote to "not guilty" in support of Juror #8. What was his reason for doing so?

Juror numbers 9-respected juror number 8’s sense of autonomy: he felt that juror 8 was able to think independently. Juror number nine also notices Jurors who secretly felt uncomfortable with their guilty vote. He also had doubts that the old woman had time to put on her glasses when she was in bed. He questions if the old woman really saw what she claims to have seen.
