Jacob has successfully completed Ms. Attaway's two assignments and ready to take over the next to target to gain her full trust. The Third part of the Sequence 5 is Survival of the Fittest and let's uncover what's the real purpose of Ms.Attaway with Jacob.
Jacob visits Ms. Attaway's Carriage to take on next Mission, but before that she wants to celebrate the success of first two assignments with a wine. Then she explains Miller's works and how you could put an end to this by Assassinating him.
First head to Miller's contraband, but without touching River Thames(side objective). Once you reach Contraband you need to Destroy the contraband with the use of Dynamite crates. Also a side objective to Sabotage 2 contraband at once. To do so go ahead and kill all the enemies on the ship and then complete the objective.
After Destroying Miller's contraband, it's time to Assassinate Miller and finish this once and for all. Head Straight to Miller and Assassinate him. Miller at his death bed informs us how Ms. Attaway and Starrick are related to each other. They both are actully cousins who wants to rule London and now you need to find Ms. Attaway to clear this cloud.
You find Ms. Attaway and Starrick are having a conversation about her success. How she is happy not marrying and built her own empire and an Assassin(you) helping her for a Templar's cause. She agrees to hand over the Omnibus to Starrick and crack a deal with him. Thus Ending the third part of Sequence 5: Survival of the Fittest.
