An Intruder?

Eva replayed a certain time frame from yesterday night's recording in slow motion, and Taya saw something strange when she observed the things in the room, especially a moving ball toy which continuously oscillates on its own.

"The frame in that particular second...it seems like...." Taya was surprised to see that the oscillating ball toy stood still suddenly in that second. This was not something that should happen normally since the ball was supposed to move to and fro on its own like a pendulum.

"It froze," Eva added with a frown and continued, "But everything continues perfectly the next second. I just don't understand if this is some visual bug or…"

"No...this cannot be a bug...Strange things that are beyond our understanding are possible in this world. And if it was really a bug, then where did my samples go?" Taya mumbled in a dispirited tone as she rubbed the sides of her head, feeling a headache about the current situation.
