Refresher Course

Refresher Course was a virtual training mission, relived by Desmond Miles in 2012 through the Animus.

Description
After the Grand Temple triggered a Bleeding Effect in Desmond Miles, through which Juno told him to find a key, he collapsed and entered a fluke state. William Miles, Rebecca Crane and Shaun Hastings placed him in the Animus, where he familiarized himself with the updated software installed during the time he spent in a coma.

Dialogue
Desmond found himself in the White Room. The Animus loaded a basic terrain layout. Desmond made his way over a few obstacles. Desmond did as he was asked, climbing along the ledges to the freerunning training area. Desmond proceeded along the path to the next area, containing two enemies. Desmond assassinated the two targets and continued forward. Desmond continued through the course, eventually reaching the end and fully synchronizing with his ancestor, Haytham Kenway.
 * Rebecca: Okay, Desmond. While you were, uh, visiting Constantinople, we picked up a software update for the Animus. I'd like to run a couple of quick tests - make sure there aren't any major issues.
 * Desmond: Alright, what do you need me to do?
 * Rebecca: We'll start simple. Walk to the marker over there.
 * Rebecca: Okay Desmond - let's practice climbing on these objects.
 * Rebecca: Free-run your way through this little obstacle course.
 * Rebecca: That's a constraint. These are optional objectives that raise your synchronization rate. Alright Desmond. Follow the onscreen instructions and kill the two templars.
 * Rebecca: All you have to do here is jump the gap.

Outcome
Desmond fully synchronized with his ancestor, and proceeded to relive his memories.
