Previously: Cali finds out that the rest of her Order and even Dr. Alphys have been helping her and she didn't even know it. She also tells Deos that she's been in love with him and much to her happiness, he shares those feelings and wants them to become closer. After that he and Frisk participate in a Quiz Show hosted by the narcissistic Mettaton, which involved an on-camera revelation of Dr. Alphys' feelings for Undyne, which made her turn red with embarrassment, once Deos told her that she watched the whole thing.

(Lab)

While Dr. Alphys was red and curled up on the floor, Cali spoke her opinion "Deos, did you make sure that Undyne was watching Mettaton's show?!"

"Yes, after she told us that she'd leave Frisk alone and showed us that reacting violently isn't the only solution to her problems and that the death of either of us isn't needed, I thought that I'd give her something that she'd like." Deos said.

"Deos...I didn't think that you were that devious, no harm was done." Cali said with some happiness in her voice."

Dr. Alphys got up and was more assertive than she usually is "HOW COULD YOU DO THIS TO ME?!" then she realized what has happened and that she'd have to tell Undyne eventually, she felt bad about that "S-Sorry, I shouldn't have said that...I g-guess you wanted to h-help me" she briefly looks at the communication link to the surface connected to her computer "...b-both of you are."

Frisk then receives a call from their phone, the phone that Toriel gave them, it was Papyrus "GREETINGS, FRISK! UNDYNE WAS WATCHING METTATON'S QUIZ SHOW AND SHE WAS STUNNED WHEN DR. ALPHYS CONFESSED HER LOVE TOWARDS HER!"

"I did NOT confess that! Mettaton said it!" Dr Alphys said with uncharacteristic assertiveness.

"SHE THEN SCREAMED SOMETHING THAT I, THE GREAT PAPYRUS, COULD NOT MAKE OUT AS SHE RAN OUT OF THE HOUSE AND IN THE DIRECTION OF WATERFALL!" Papyrus said.

"She's probably headed here" This made Dr. Alphys wide eyed in fear "...right now just keep watching and you'll be seeing more of us". Deos said.

"OF COURSE, DEOS!" Papyrus said, he then hanged up.

"She's c-coming h-here?!" Dr. Alphys said in a terrified tone.

"What fortunate timing..." Deos said.

"You agreed to show her what's down there, Alphys, you might as well do it now." Cali said.

"W-what?!" Dr. Alphys said, more nervous than ever.

"Whatever it is that you are hiding, it is clearly killing you and unlike me, you lack the ability to stop aging, the sooner you talk to Undyne about this, the sooner that you can tell the rest of us." Toriel said with a compassionate tone, she didn't want to be harsh towards her as she didn't exactly have the moral high ground.

"Y-yes..." Dr. Alphys said, she then saw Frisk and Toriel's phones "Where did you get those phones!? They're ANCIENT! It doesn't even have texting. W-Wait a second, please!" she then quickly made a few modifications within earshot of them that sounded noisy and came back with them looking different, handing them to Frisk and Toriel "Here, I upgraded them for you. I also gave you my p-phone number, in case y-you need h-help, it can do texting, items, it's got a key chain..."

"Yeah, thanks for that and for the signing up to the underground's No. 1 social network and yeah, you're officially friends with Frisk, as for Toriel...she's still unsure about you for now..." Deos said, it was then that the doors opened to reveal Undyne, who was close to collapse, Deos handed her some water, which she drank heavily.

"Thanks, I needed that." Undyne said, she then turned her attention towards Dr. Alphys "Was what Mettaton true? Because if that smug metal box was making that up, I'll turn him into scrap metal!"

"No, it's true..." Dr. Alphys said.

"Why keep it in for so long?" Undyne asked.

"I...I have issues." Dr. Alphys said, with some shame in her voice.

"What kind of issues? Because if anyone is bothering you..." Undyne said with a hint of anger towards an unknown source.

"N-no, it's n-not that..." Dr. Alphys said, holding up her claws to try and calm her down.

"What Dr. Alphys was trying to say was that...it's better if she just shows you." Deos said.

"This way, Undyne" Dr. Alphys said as she beckoned Undyne to follow her to an elevator, Undyne follows her and they descend to the lower levels.

"That last question had no right or wrong answer, Asgore had a similar response." Deos said, this made Toriel wide eyed with shock.

"WHAT?..."

"It was likely before she met Undyne, someone who is much more with her reach, I did say that she was a BISEXUAL reptilian otaku, who knows...she might've seen a picture of you and some point and found you cute." Deos said, this made Toriel drop her mouth in shock at this thought, Frisk laughed a little at that, Toriel then changed the subject.

"You know what is down there, don't you Deos?"

"Yes, I do...but it can wait until Dr. Alphys is done telling Undyne, we'd best move on through the rest of Hotland, we can't keep Mettaton waiting...there's also our business with 'King Fluffybuns'..." Deos replied.

"Yes...there is also two more children to account for, we have best get going." Toriel said as she entered the Dimensional Pocket Amulet.

"I'm sure that Dr. Alphys will be keeping you informed of our progress through Hotland, when she gets back from the True Lab, don't worry, you'll probably not be missing much, just Sans selling 'hot dogs' and some unintentionally dangerous monsters, that's about it...oh and Asgore didn't kill at least four of the them personally, I'm not sure about the others." Deos said.

"Okay, let me know how the other two died and I'll base my view on him on that, bye Deos." Cali said, with some cheerfulness towards the end.

"Bye, Cali." Deos replied as he and the others continued onwards through Hotland through the other way out of the Lab.

(Hotland)

As they walked along the path lit by the lava all around them, Deos continued to speak "No, we can't go through the two Royal Guards, they won't let anyone pass and they might try to kill either of us humans."

"Ain't that a shame (!)" Flowey said.

"Why am I called 'GoatMom01' on this...social network?...What even is a social network?" Toriel asked with confusion in her voice.

"Ah...perhaps I should explain what that is and how it works...also, how texting works." Deos said, he then started to explain both.

(True Lab)

"I haven't been down here before, why is it so dark?" Undyne asked, unsure about her surroundings.

"T-There's a reason for t-that...and other things." Dr. Alphys said with a tone of shame in her voice, Undyne knelt down to around Dr. Alphys' level, it's clear to her that there's something troubling her reptilian friend, which troubles her as well.

"Alphys, what's been going on down here? What could be so bad that you're keeping me out of here?" Undyne said, with a compassionate tone in her voice and an usual calm.

"I can't keep hiding this, it'll k-kill me, I have to s-show you something, something that I should've shown you sooner. Dr. Alphys said, she led Undyne to what appears to be a hospital ward, where in the beds were a group of amorphous brings, this shocked Undyne as she wasn't expecting this to be down there.

"Amalgamates, that's what they are." Dr. Alphys said, although she couldn't look at Undyne.

"Where did they come fro...isn't that Snowdrake's Mom?! What's been going on down here?!" Undyne said with confusion in her voice.

"I'll s-show you" Dr. Alphys said, as she led her to a machine that looked like a skull. "This is the D-T Extractor, I used it t-to extract Determination, the substance that w-was in Deos, which gave h-him a p-power boost."

"What has this got to do with those Amalgamates?!" Undyne asked.

"I'll show you the logs, say what you want to tell me after you've seen it all." Dr. Alphys said, not being able to keep in the shame, she led her to the video room, which contained some video logs and text based documentation that's simple enough for her to understand.

What other setbacks are ahead of them? How will Undyne react to what she finds out in the True Lab? Find out in Chapter 20: Dark Truths
