So yeah I watched the new episode yesterday. And yes, I was crying.

I also find it interesting that Louie was originally named Rebel, and he was the only triplet who didn't believe Della was his mother at first. Which is somewhat rebellious. Especially since when Dewey first revealed to his brothers that he knew the information about their mom, Louie was the most shocked by the news. (In the episode when they visit Scrooge's parents)
