The Mystery of 'Uncle Jake' Solved

It felt odd that Elliot's imaginary friend was "Uncle Jake," since the name seemed to come out of nowhere.

Then Kelly discovered the origin of Uncle Jake — "Usual Suspects"-style!

She was reading Elliot one of his current favorite books, "Oh, the Places You'll Go," when she came upon this page.

It's probably the most poignant page of the book, Kelly says. So it's not surprising that Elliot would take something from this and conjure up an imaginary person.

Still, it's funny where kids pick things up.
