"So this is why they call it WATERFALL…" Wander muttered, wading waist deep in a 'river' of water. He was referring to the large waterfall that was flowing next to him. "This is really neat! We really could use a great swim right now.

Sylvia sighed and rolled her eyes. "Wander, we don't have the time. After all we need to get out of here! Remember?"

"I know, I know… I just want to take a little break. We haven't stopped since we were at Toriel's house. You gotta take breaks every once and a while and rest. Besides, the water's fine! Hop in for just a minute, besides we gotta wade through to get to the HOTLANDS anyway, don't we?" Wander asked, and Sylvia groaned, before dipping a toe into the water, she yanked it back at the strong feeling of cold.

"I thought you said that the water was warm!" Sylvia shouted, and Wander shook his head.

"No, I said that the water was fine. So just come one, and let's move on!" Wander shouted. Sylvia sighed and reluctantly entered the cold water, before rushing through to the other side. Wander rolled his eyes, before happily trudging his way across the pond. It didn't take long for them to trek through the several more placed ponds, until they came across a large and tall patch of grass. "Ooh! Check it out, Sylvia! I bet someone could get lost reeeeaaal easily in there." Wander said, before the duo crossed through. There wasn't anything very interesting about WATERFALL and nothing that really stuck out among the dark blues and grays. There was however a small bird was kind enough to carry them across the river, despite the fact that they were three times his size.

The duo continued their travels, and for the first time since they'd entered WATERFALL, he looked up, and let out a loud gasp. Sylvia, having heard this, quickly prepared herself for a fight, until Wander grabbed her head, and tilted it up as well. On the roof of the cave were hundreds of shimmering and shining stones that twinkled in the low light, almost like…

"Stars." Sylvia whipped around, prepared to attack, until she noticed that it was Sans standing there. "Sorry if I scared you." Sans grinned, looking back up. "Beautiful isn't it? I remember coming to the WISHING ROOM with my brother a lot when he was younger." Sans muttered and Wander let out another gasp.

"You have a brother!? What's his name? What's he look like? Where's he from? What color scarf does he wear? What-"

"Look, Wander… He's…" Sans paused, and clenched a fist before relaxing his fingers. "I haven't seen my brother for a very long time. But I've, uh, got a photo I could show you…" Sans reached into his jacket and fished around for a moment, before pulling out a photograph. Wander wasted no time in taking the picture, and began to study it intently. He could see Sans, only he was wearing a pair of pink slippers, and wasn't wearing the scarf. Standing next to him was a much taller skeleton, he wore strange looking armor, a pair of crimson gloves, and a pair of matching boots, along with the red scarf that Sans wore now. "His name was Papyrus… And… I haven't seen him in years… He… Went off to the CAPITAL to accept his position as a royal guard. Yeah… T-That's it…" Sans said, however Wander noticed that Sans seemed upset over something.

"You miss your bother… Don't yah?" Wander asked, and Sans nodded. "Well don' you worry none. I'm sure that he misses you too, and once you see him again, I'm sure he'll want to give his little brother a big 'ol hug!" Wander shouted, but heard something dripping against the floor and noticed that Sans appeared to be crying. "Whoa… You sure you're doin' all right there buddy?" Wander asked, and Sans nodded.

"Just…" Sans stopped and opened his mouth, before closing it again. "Just can't wait to see my brother again… Not to mention… I'm the older brother…" Sans chuckled before saying "You two should get going again… Especially if you want to reach the Barrier."

Sylvia tilted her head and asked "You mean the exit right?" Sans nodded and Wander gave a warm smile, before the duo exited leaving Sans standing there alone.

"HqEz SlPj UjK nErA wQsC hYa VeDsX?" (1)

"I don't know Gaster…"

"Fh SlK wErB nJtU eY cDg?" (2)

"N-No! I don't want them to…"

"HyEn PoLg ZeLj YuN DiJm." (3)

"I… I know Gaster… I know…"

Wander and Sylvia were quickly able to find themselves near the exit, but noticed a large neon sign hanging along the wall, it read "Welcome to HOTL-" The rest was cut off. "I'm guessin' this leads to the HOTLANDS, right Sylvia?" Wander asked, and Sylvia nodded, but just before they left, they heard another ghostly voice.

"If YoU tHiNk I'm GoNnA gIvE uP hOpE, yOu'Re WrOnG. cAuSe I'vE... gOt My FrIeNdS bEhInD mE." This voice sounded strong, determined and ready to fight until the bitter end. Wander and Sylvia exchanged nervous glances before stepping through the way to the HOTLANDS.

"Exiting WATERFALL, and learning about Sans' brother fills you with DETERMINATION."

Author's Note: Sorry about the long wait for this chapter, I was having a difficult time thinking of things they could do in Waterfall, since it doesn't really have as much going on as the other places in Undertale, so that's why this chapter is so short. Don't worry I'm still leaving the Gaster Translations below.

Gaster Translations:

(1): When will you tell them the truth?

(2): Do you want them to die?

(3): Then tell them the truth.
