The other day I was thinking how odd is the character of Wedge. Dramatically it makes no sense but its one of those awesome universe building things that made us love the Star Wars Universe.
But think about it, why was Wedge in A New Hope? He is barely introduced and suddenly he is a big part of the plot. Biggs had his (deleted) scenes and he works as Luke's friend and partner. But Wedge just appears out of nowhere and he is the only one called by name.
But more importantly, he doesn't die. Every single pilot is killed one by one to leave Luke alone against the Death Star but for some reason this one pilot that we don't know escapes instead of blowing up. Imagine you are watching this for the first time and you saw Wedge running away... it would be weird to see that and not have a payoff, not have him reappear.
He is such an oddity...
And in the next two movies he appears again. He is never ascended as a character, we never see his arc or learn anything about him he is just there. You could write him off of ESB and ROTJ, he is only there to do things that any other movie would have left to the main characters. Any other movie would have had Biggs save Luke from that TIE. Any other movie would have had Luke destroy the AT-AT. Any other movie would have left the Falcon alone by the time they reach the Death Star core to show how desperate that moment was.
But he is there. And he is awesome. I'm sure noticing Wedge throughout the movies is one of those little things that made many of us appreciate this saga more. At some point knowing who Wedge was was the entry level to be a Star Wars fan.
