The very fact that they have the elderly couple in the final scene proves that the older ones are getting frustrated at the delays..... This seems like a deliberate attempt to keep them hanging on.....
Quite right. If you look at the broadcast earlier on and see the account of the elderly couple in Etheopia this was exactly the same They spent years in full time service, went to Bethel and are now pioneers - clearly after having been chucked out of Bethel for being too old. Their message was one of support for the org and accepting this change which is clearly the message for all those others in the the same boat or witnessing it.
