To be honest, Scrooge never stopped caring about family, he just felt like it was his fault delle went missing and was making sure it wouldn't happen again.
Oh yeah now I remember they’ve reused the same dialogue for two different episodes I love the new ducktales as the old triplets sounded like they were on drugs yet they were voiced by the same voice actress who voiced Minnie Mouse
Guys, quit teasing Scrooge. I think he does know his name but he probably likes to tease with Dewey that's all. IDK maybe he does forget Dewey's name but come on, he's over 80. So of course he going to be forgetful once in a while. After all, he still has so much to learn about the kids so give the old man some time.
