You walked into some sort of laboratory. As you walked in, you looked around, seeing that it was somewhat similar to Alphys's laboratory, but a bit different. In the middle of the room, you saw Sans, or, to be more specific, Science Sans, working on something...You took a step closer, causing Science Sans to hear you, which he turned around, and saw you.

"Oh, hello there!"

Science Sans said happily, as he stopped doing what he was doing, and fully turned towards you.

"What can I help you with, sir/miss?"

Science Sans says happily again.
