Davey is a character I barely know. I will try my best to analyze him.
Davey is basically the Newsie I would like to call the “new” Newsie. He is the only one of the Newsies who actually has a family. He arrives to the newsstand with his little brother, Les. He became a Newsie because his father got injured during his job and was laid off because of it. Davey started off as shy, but as time goes by, he interacts more and more with the Newsies.
Whenever Jack doesn’t know what to say during the strike, Davey does the talking. While Jack is the leader, I feel like Davey is second in command. Davey helps Jack deal with the inner conflict he is going through in act II at times. While Jack began the strike, Davey was the one who came up with the rally.
