Have you ever noticed how Rudy's lines are Nathan's lines? Rudy IS Nathan. just in a different form. it's because Nathan was never supposed to leave the show. as much as i love Rudy. Nathan was better imo.
I’ve noticed some jokes are quite the same. Like the thing with the Cornetto. But Rudy is not Nathan, in any way. He’s a complete different character and he’s not like an extension of Nathan’s character because they had to write Nathan off. Sorry, I think I disagree.
