This was in a past episode which was filmed but was unfortunately cut. So sad they didn't show it.
The man in uniform is Finn’s dad played by a French-American actor Sebastien Cuk. His photo can be seen in 2 episodes Pilot and Home. The baby Cory is holding is Finn as a little baby. I hear the father-baby flashback scene was filmed and supposed to be included in Home, but finally and unfortunately it was cut out. What a cute bb Finn! and Sebastien is as tall as Cory. Finn’s height is inherited from his dad.
