It wasn't the most productive exchange of glances Rel has ever had. Upon nearly catching up to the trio to which she found had just assembled moments before, her eyes and those of a familiar individual briefly locked to each other. She recognized this individual as Frisk's assistance; Skylar. Curious though what she was doing way out here, especially at entrance of her long abandoned home. It really didn't take Rel long to determine the simple answer, especially when Frisk had just vanished as of late. The other individuals accompanying her, or what it appeared to be just meeting up was another human and a fellow monster; she knew neither of their names unfortunately but mused the idea that would soon change.

Before a question could be asked or a conversation kick started from either entity, Skylar had proceeded ahead and then leapt into Mt. Ebott's circular cavern into the Underground. This further reconfirmed Rel's suspicions but also denied her intent on investigating the unnatural disturbance she had sensed before. "H-hey!" Rel yelled, reaching her one of arms out as gesture to stop as group began jumping into the Underground.

With an annoyed groan, she spread all four of her arms out and summoned her up her powers as she projected a aura glistening of different colors as if her form was that of a prism. The light she generated encompassed her image and folded in of itself, mutating her three-dimension being into a flat two-dimensional aspect before shooting into the air. The contorted vector dived into the hole, quickly ricocheting along the walls before finally meeting the familiar ground. With one more deflection against the earth, the line bounded over everyone and slammed directly into their path. Rel eventually materialized back into the four-dimension from the spasming shape before it converted itself into a wall, preventing access deeper into the underground.

"Sorry, I don't mean to impede you," Rel began has her gaze landed on Skyler specifically though talked as if it was meant for everyone, "I can appreciate you trying to find Frisk and I won't stop you from doing so. But..."

Rel then pointed in Skylar's general direction as her visor's arriving visuals still sputtered like before, "While I am unsure that is any of you noticed it, I detected a quantum disturbance minutes before you came down here. That kind anomaly as we know is unnatural to both monsters and humans and doesn't occur just randomly. Care to explain what that was all about?"
