SPOILERS! Could the Ending of CHUCK Be through Sarah's Latest 'Mission'?

Tweet

You know that Sarah recently 'downloaded' the Intersect into her brain, but--like it did with Morgan Grimes and like I think it did with Chuck--the programming has a malfunction that makes the user lose part of her memory. So now Sarah's memory has her believing she's a special-agent in the enemy agency, and her next mission is (you guessed it) "Kill Chuck Bartowski" (which doesn't make sense--except as it tests Sarah Walker Bartowski's allegiance to the enemy and eliminates the possibility of Chuck & the good guys saving Sarah before Sarah can steal the last Intersect-version for the enemy). Anyway, do you think that's how the series will end---with Sarah successfully finishing Chuck off?
