- Aw, Look! They Really Do Love Each Other: Reflecting back to the first case they worked together, Alan tells Don and Charlie that he's happy about them working together because it revealed and strengthened a bond that he hadn't been sure they still had.Alan: I was afraid before [their first case] that you had grown so far apart that I was the only thing you had in common. I figured after I died, you might spend years without seeing each other, but to tell you the truth, I'm not worried about that anymore.
