This how the Season 8 finale should be:
DESTINY or SUPER
*Opening scene would involve Clark saving a Luthorcorp(or LexCorp) experimental space plane from crashing, almost revealing his powers in public (akin to SR).
*Lois writes an article about it, titled "MYSTERIOUS 'SUPERMAN' SAVES SPACE PLACE".
*Chloe,Kara and/or MM confront Clark about almost revealing his secret.
*Clark finds it difficult to use his powers for good without revealing them. Chloe suggests to use a new identity.
*Clark practices flying and using the Meisner technique to distinguish from his mild-mannered self and his heroic self.
*Kara makes a Kryptonian garb with a red cape for Clark to use for his superhero identity.
*Climax: Clark covers a story invoving a West African conflict (ala Birthright) and uses his powers to save the day, without revealing his powers.
This is where it gets more Superman-ly
*Clark and Lana meet at the Kent Farm. Clark said he's has something important to say. Lana hopes that it's a marriage proposal. Clark tells her that he had to leave Smallville to help humanity as a whole. Lana give Clark a sad goodbye kiss (like a brother), thus being left heartbroken and alone. (ala Byrne's MOS).
*Clark takes the octangonal "key" and teleports himself and the suit Kara made for him to the Fortress.
Final scenes are in bold:
*Clark sees his Jor-ELr's face for the first time (similar to a white-haired Chris Reeve). Jor-El says a speech involving "son becomes father, father becomes son".
*Then we see the exterior of the FOS in the sunset while a red-and-blue blur (Clark/Superman) emerges out of the Fortress, taking flight.
*That blur can be seen flying through Smallville and heading straight for Metropolis.
*Finally, the camera pans forward at the red/blue blur, revealing a Superman silhouette like this:
