He is likely original. I didn't interact with him much. I had him for a long time though. I'm giving him away, so if anyone needs another lazy villager, you can have him. He moves on the 19th.
Can I take him? You see, I like to get villagers that I love but didn't quite make the dreamie cut (Jeremiah was 14th overall) and I love to enjoy them in my town for a while. I would hate for Jeremiah to be voided, so when he leaves my town I WON'T sell him; I'll give him to someone who has him as a dreamie for free. I can 100% understand if you don't want to give him to me though
