Yeah, but Asgore seems oblivious in the neutral ending as well; Small Shock plays as we approach him. Flowey might be the only one who ever told Asgore about the human, while Alphys vaguely likes us so long as we're not dust-lust aficionados. She's probably so forgiving because of her own mistakes.

However, Undying points out that Alphys will contact Asgore - what happened there? I don't think Alphys likes us in the dust lust route, which is reinforced by the Alphys neutral ending. Maybe Alphys watched Undyne return from death and thought that DT could grant that ability to someone else so that the protagonist could be stopped.
