"Lee Grant" is Luke's new identity. And it not only comes along with a whole backstory but also a whole new wardrobe.
The real Lee Grant recently died and Jen's dad was able to get the fake I.D. super quick.
Apparently there's a secret society that helps third children get new identities, like an underground railroad for shadow children.
But there's a catch: he has to leave his family and is off to a year-round boarding school.
Luke thinks back to when he finally spilled the beans to his parents. Naturally his mother ended up hysterically crying and his father stoically agreed that a new identity was the only chance Luke has for a normal life.
For two days afterwards, Mrs. Garner spent all the time she could with Luke, pumping him full of memories.
But now Luke is saying his last goodbyes while pretending he's someone else.
Mr. Talbot indicates that the charade starts now since he's still bugged.
Driving away, Luke thinks about singing Jen's praises when all the third children are freed.
Luke looks back at the farm until he can no longer see the only world he's ever known.
