The thing that bugs me the most about Alphys’ and Sans’ dialogue in the pacifist ending is that, to get that ending we had to get Alphys to tell everyone the truth about the amalgamates and teach her how to stand up for herself and her actions and be honest. But then, when we think she’s finally come clean with everything:
Undyne: “Oh man!!!” “We’re gonna be able to watch anime online!?“
Alphys: “Of course, Undyne!” “What do you think we’ve been fighting for all along?"
Sans: "yeah, what do you…” “whoops."
Alphys: "Jinx!” “I knew you were gonna make that joke!"
Papyrus: "WAIT, ALPHYS, I DIDN’T KNOW YOU KNEW SANS."
Alphys: "Well… I…"
Sans: "doesn’t everybody?"
Like!!! We talked about this, Alphys!!! This is exactly the sort of thing youre not supposed to do!!! All of our work and support didn’t do anything!!! How dare you!!!
Actually, I appreciated this for almost the exact same reasons! Changing behaviors you’ve had for years isn’t as simple as flipping a switch. It’ll take time for Alphys to get better at being honest all the time. Though I will also note that whatever’s going on there is also Sans’ secret, and there’s a big difference between not keeping your own secrets and not keeping someone else’s.
Iirc the commonly accepted reason as to why Alphys took so
long to finish Mettaton’s body was that because if she did, he’d leave, and
some details have me thinking that while this was true, and Mettaton definitely
picked up on it, it wasn’t the whole story.
First some odd details. This isn’t required for the upcoming theory to work,
but it lays a good groundwork for it. Warning: long and image heavy, also
blatant metaphysicsery.
Carefully,
as if afraid it’d decide to slam shut right in her face, Alphys
pushed open the door to the library – not the librarby,
it was worth noting. The
monsters
had made sure to get that right this
time.
She
breathed a sigh of relief when she poked her snout into the doorframe
and the entire library didn’t turn around and annihilate her in a
single shared stare of disdain.
In fact, nobody seemed to notice her at all.
Even Undyne, who wasn’t
behind the front desk like usual but seated on a rickety wooden chair
in front of the entrance, hadn’t noticed her. She hadn’t as much as
glanced up from the over a dozen children, seating cross-legged or
many-legged or hanging from the ceiling or too tiny to see more than
the pillows they were seated on, all staring rapturously up (or down) at
her.
So
Alphys stood awkwardly in the doorway, refusing to even let the
chilly winter air outside move her forward. She just stood there and
quietly admired how Undyne looked with her bright red hair tied back
into a bun, even though she looked almost as silly wearing reading
glasses over her eyepatch. She didn’t even have vision problems,
outside of the obvious one.
But
eventually, Undyne’s eye, that surprisingly soft, gentle yellow eye,
turned up just long enough to meet hers. Undyne stopped whatever she
had been saying, her eye widening, and Alphys couldn’t keep herself
from swallowing back a breath as she stared back at her.
