The third and final time happened only a few days after the second.
"FRISK! FRISK!"
Alphys and Undyne had more or less burst into Toriel's home one morning. Each practically shaking with excitement.
"FRISK GOTTA COME EMERGENCY NOW!"
Undyne basically carried Frisk out of the house with Alphys rushing close behind. The two shouted reassurances to Toriel that they'd have the human back by lunch.
Whether or not the goat mother had even given her "okay" was lost to the chaos of the two loud girlfriends.
"MEW MEW KISSY CUTIE 3 FRISK! THEY MADE A THIRD INSTALLMENT WITH NO PRIOR NOTICE TO THE PUBLIC!"
Frisk nearly had to cover their ears in the car. It MUST have been thrilling news considering the reptilian scientist hadn't stuttered once in her entire rant.
Plus she'd raised her voice to a near shouting level, which Undyne visibly beamed at.
"She's been screamin bout this since this morning kid! Were ordered the tickets right before we left ta pick you up!"
Literally pick up.
Frisk had to smile at the irony.
Normally such a happy energy coming from their friends would have filled the small human with determination.
This time though was different...they felt an uneasiness in their heart.
Like something awful was going to happen.
They tried to decline at first.
"What! Kid?! You love MEW MEW KISSY CUTIE!"
Undyne almost looked like she was pouting.
"Y-yeah Frisk! We w-wouldn't wanna see it if you d-didn't come with!"
Alphys WAS unapologetically pouting.
Both girls clearly wanted to fangirl over the movie, but only with their favorite human at their side.
Who was Frisk to say no?
Besides the two girls had been so busy with setting up Alphys new laboratory lately, that the human figured a few hours away from reality would do them all some good.
Maybe even an hour or two of nothing but animation would make them forget the visions.
So despite the ominous feeling that laid heavily in their stomach, Frisk put on their best grin and accepted the offer without any further hesitation.
Anyways what kind of excuse was there to give?
That they didn't want to trouble them?
They were already in the car!
That they didn't feel well?
No, Toriel would rush them to the doctors.
That they were nervous? That they were having night terrors that happened at any time? That they felt like crying over actions they never even committed?
...That everything they saw felt more like memories than imagination?
The human shook away the idea.
The human never laid a hand on ANYONE during their time in the Underground. It was a fact! Not one monster had received anything other than mercy from them.
Hell even when they had reentered the surface Frisk had never once been anything other than a kind soul.
And yet somewhere deep down they knew it all was linking too well together.
The smile, the red eyes, the laughter...
Something about the feeling Frisk felt after every recollection felt sickeningly familiar. To the point where the small human was surprised as to why Toriel had yet to ask why they looked so nauseous?
Then again it wouldn't have been exactly nice to respond with "Oh you know cause I murdered you and it kinda shook me up a little. Don't worry I'm fine."
No that would probably send their goat mother into cardiac arrest if anything.
Instead Frisk sucked it up and allowed their nerves to bury deep inside. They wouldn't want to inconvenience their family. Perhaps their determination alone could probably bare the burden.
At least. Thats what Frisk had thought until the movie had come close to ending.
For at the final climatic moment, the hero of the tale was revealed to be the antagonist all along. The one the whole audience had been routing for, the savior, the master of everyone's fates...turned out to be a murderous demon in disguise.
Alphys nearly had a conniption.
"T-this is awful! HOW COULD THEY DO THIS TO MEW MEW KISSY CUTIE?!"
Undyne threw her popcorn at the shushing audience members behind her and slung her arm around her girlfriend's shoulder.
"Aw shut ya traps back there! My girl can be mad if she wants. Little creep stabbed em all in the back without even blinking!"
"I-I DEMAND JUSTICE FOR KISSY CUTIE!"
The two were so lost in the final scene's action sequence that they both overlooked Frisk. Who had such an iron grip on the chair arms that the metal was beginning to bend into their hands.
It all was suddenly coming back.
The timeline where everything had fallen apart.
When they had killed everything. When every monster feared their name, and saw only merciless red eyes before being chopped to bits.
When Toriel had been cut down. When Papyrus had fallen to ash. When Undyne had melted into nothing. When Alphys had crumbled upon seeing Mettaton's blown apart remains. San's judgement. San's battle. San's final words. Asgore's tear filled eyes. Flowey's final plea to live. Chara. Chara. Chara...
Frisk saw it all. They relieved ever last moment of the hell they helped create.
They remembered everything.
They saw it.
Everything...
Neither of the girlfriends noticed Frisk rush out of the theatre.
Until it was too late.
