- Where else would he be?
- The has been said a lot and it may actually be Word of God but I'm putting it here anyway. Ghostwriter was first in Jamal's basement. His first words were "Help help. Where are the children are they alright?" He doesn't know what things like cornflakes, Elvis Presley and Mickey Mouse are, suggesting that he died before the twentieth century. He remembers being chased by barking dogs before he died. It sounds like he was a slave who was trying to escape with some kids, was chased by slavecatchers and was finally caught and killed.
- According to Word of God in in a 2010 interview, The Ghost Writer was a runaway slave who taught other runaway slaves how to read before being killed. Whether he was Jamal's ancestor is up for debate.
One of the reasons the team suspects Spencer is because they find out that one of the theft victims was able to get her tape player back by telling the fence that Spencer sent her. This suggests that he felt bad about what Kevin was doing and wanted to help. He also backs up Alex when he confronts Kevin about his drug problem suggesting that he was worried about Kevin too. Spencer does seem to want to do something about Kevin but is afraid to, especially because he's been friends with Kevin for a lot longer than Alex has. With some gentle nudging, the team could have gotten him to admit everything and the case would have been solved a lot sooner. This shows that even the Ghostwriter team can screw up.
- She bumps into him a few times and it looks like it may be on purpose. She says at the end that she became Max Mouse because nobody notices her (being a Shrinking Violet ) and she wanted to get attention. Maybe she also had a crush on Alex but didn't believe that he'd actually want to date her so her so she did what she thought was the next best thing. She knew he was a detective and that if she used her computer skills to reek havoc, he'd try to catch her. Therefore he was focusing a lot of attention on her even if he didn't know it and that thrilled her. It wouldn't be the only reason she became Max Mouse but could have added to her motive.
