The last song Lea - Rachel sang in the very last episode "This Time" was written by Darren Criss - Blaine.
The words on the top of banner on the piano Blaine plays for his and Kurt's duet at the elementary school, "Hope will never be silent.", come from one of USA's most prominent LGBT civil rights leaders, Harvey Milk. He believed in a country, a world, that would honor the God-given rights of all individuals, gay or straight.
