Noelle says
>* I'll, um, go bring my dad back to the hospital.
when she leaves the Church before this. You can visit Rudy at the hospital yourself before you go to Noelle. This statement doesn't make sense in itself - it would be "just me here" if she was at home with her father. It's just a small error.
>Except Carol arrives at the exact same time (early) even in weird route where there was no phone call
We don't know what happened in between >EQUIPing Noelle and Kris flipping out in the bathroom. We're only told that Susie found the guitar on her own, Asgore caught her with it in the living room and kept her busy talking to her until Carol showed up.
It's possible that Kris still alerted her to come home - I find it unlikely that Kris was in any state to do that, but they still found some time to wipe their phone like they do in the normal route. It's possible that Carol was expecting Kris maintain contact, and when Kris failed to report because of what we did, she took control of the situation. It's also possible that Asgore alerted her when he found Susie in the house, or even that Noelle herself called her after the experience she just had. We don't know, but we can't say nobody called her either. It seems pretty farfetched to argue it was just a coincidence and the person who said "I'll be right over" never showed up (or was a bedridden man who was already there and did nothing to affect the situation).
>We also have Carol calling Kris at the end of weird route, and she doesn't do the black speech groaning that whoever is talking with Kris during the visit does
If the black speech is meant to be an in-story thing and not just the speaker's identity being arbitrarily obscured from us, then Carol is just using a voice changer when she's talking to Kris about their evil plans because she knows that the SOUL could be listening. That wasn't necessary in the Weird Route, where she's speaking in her capacity as Noelle's mother.
