Yeah, it is kind of weird
Aldebaran was friendly to Ram in Arc 1, but he assumed that she was dead in Arc 3, and lost his cool when Rem told him that she was alive
He also didn't know that Rem existed, he called her Ram during their encounter in Arc 3 until Rem corrected him
As much as I don't like the "the re zero world is in le big loop" theory, Aldebaran having vague and slightly incorrect knowledge about people that he didn't met makes me rethink my approach
