The Unworthy Brother

The Unworthy Brother was a virtual representation of one of Edward Kenway's genetic memories, relived by a research analyst at Abstergo Entertainment through the Animus.

Description
Edward opened a pigeon coop and accepted a contract from the Assassins.

Dialogue
Edward traveled to Fort Chinchorro and located the pirate captain. Edward killed the captain and escaped the area.
 * Captain: Many men's afraid of Kenway. "Devil," they call him. But I got one thing he don't have: this fort. I'd love to see the "devil" try to get past my men. He won't, of course, but if he did, oh I'd show him hell.
 * Pirate: I bet you would.
 * Prisoner: If you'd ever fought the, then you'd know what I mean.
 * Pirate: Tell it to the sea. I'm sick of your boasting and speaking in tongues.
 * Prisoner: It'll swallow you, and your ship with it, and any whales that happen to be nearby at the time.
 * Pirate: If it was no match for your swelled head, it don't scare me.

Outcome
Edward completed the contract and received his payment.
