Their sitting posture is impeccable, like children raised in a family of nobles.
But Edmund knows the real Thomas is a mischievous child, always unable to sit still.
The real Emily is only two years old, it's impossible for her to maintain such a posture.
"Dad, what did you do in the lab today?"
"Thomas'" question set off alarm bells in Edmund's mind.
How could a five-year-old child possibly care about their father's work?
"Just... some ordinary research."
"Oh." The child nods and continues dining elegantly.
Throughout the process, not a single piece of food falls onto the table, no improper behavior.

Late at night, Edmund lies in bed again, observing the "wife" beside him.
He notices the skin temperature of "Lillian" always remains at the perfect 37.2 degrees.
No fluctuations, no transformations.
Like a meticulously calibrated thermostat.
More terrifying is her heartbeat.
Edmund listens carefully and finds the rhythm is too regular.
