THOMAS: Back in Nairobi, it's bedtime at the nursery.
The keepers sleep in with the orphans, spending each night with a different elephant, to prevent the orphans from becoming too attached.
For Edwin and the keepers, it's one long process of letting go.
LUSICHI: When the elephants graduate from the nursery and they go to be reintroduced back into the wild, yes, I miss them, but I feel a lot and a lot of joy, to see them go back into the wild.
And so that is the happiest moment in my life, despite the missing them.
