The transition is only surprising for where the pair of them wind up, and Frisk gapes out at the view with wide eyes while Sans settles himself on the floor. They've seen space in pictures before, but to be in it is a whole other experience. Still and silent, it's several moments before they even realize that Sans is gesturing them over.

Their stomach is in knots as they settle down cross-legged next to Sans, wanting to lean against his side as they would when star-gazing back home but not daring to here. Their heart is still thumping, and Frisk scrubs at their eyes to try and dry their tears. It's hard at first, to try and decide where to start, but...maybe the beginning is the best. Sans wanted to know all of it, and...they don't have anything to hide behind anymore. He's already said as much.

"I...I woke up in the Ruins. That's always where it starts. I wake up, and Flowey is there. He talks to me, tries to--" Frisk's breath hitches for a moment, and they bite their lip. "He tries to hurt me, but Mom always shows up to scare him off. She guides me through the Ruins, an' I explore for a bit...she's always so scared when I have to leave. But...I have to go if I'm gonna free everyone."

They hadn't wanted to leave, that first time. Toriel is so kind, so patient, but the nagging feeling in the back of Frisk's mind had become so insistent. They had to move onward, press forward. They have a duty.
