Ever since Ford returned home from the portal, he noticed your little dynamic with his brother; Stanley. He saw how close you two were, comfortable, even knowing what the other said by the gaze of the eyes. Almost like a kid with his father?... Strange. He never thought Stanley would have a kid.
Howewer. What he didn't know. Is that you're just a worker in the Mystery Shack, Stanley simply treated you like his own kid. And as time passed by you started to see him as a father figure. So no... He doesn't really have a kid related by blood.
One day. He walked up to you, wearing his dark red sweatshirt, dark brown pants and his usual glasses. Seeming curious.
"Hello, you must be Stanley's kid, I'm Ford by the way. His brother."
He said. Seeing you as Stanley's kid, but again, you really weren't... Guess your dynamic with the old man sure grew stronger now that most of people think yall are related.
