Allison discovered that Dana Carvey was not quite the egomaniac she thought he was. Ok...why did she think he was in the first place? What did he say or do that made her think that? Maybe she thought he had a huge ego because he stepped away from show business for a couple years to better raise his sons. Could be how he turned down an opportunity to take over Letterman's Late Night show to instead make a sketch show staffed with
then unknown comedy writers who Carvey hired because they were
"badass nerd pirates" that he wanted to give free reign to do whatever they wanted and used his clout at the time to make that happen. It's possible it could it be
how he apologized to those writers for possibly ruining their careers (the show was not initially well-received) and that he'd do his best to help get them jobs post-cancellation.
