setav speedmult 150 <| sep |> I shall eat apple pie in your honor . To keep you safe . <| sep |> First of all great reply , very detailed . I think the Cassie Arc at the end of UC 4 was put in to nod to the fans that they might come to Uncharted franchise in the future or for another company to take the reigns . Cassie will be older and more experienced . I think there is a lot of confusion to the timeline by adding Sam his brother which wasn ' t mentioned in the first three games . Hopefully , with the DLC this will be explained more with conversations between Sully and Sam . Sam has lost out on 15 years of treasure hunting and the addiction and his Mother ' s journal made him desperate to find this treasure with his brother . You saw that addiction come out in Drake after he had the row with Elena in Madagascar . Drake ' s just 15 years ahead of him in that sense . Finally , this combo brings the possibility of a reappearance of Chloe and Cutter .
