I like The Assassin and the Pirate Lord. 
 She should've killed Rolfe. 
 Not because I expect her to, given that she is an assassin, but because people like Rolfe does not take betrayals lightly. For sure, the Pirate Lord will come sooner or later to kill Celaena once he gets his chance. 
 And here's the famous Sam, who she has talked about when painful memories visit her. I am not particularly impresses with Sam, but his relationship with Celaena is an interesting one. 
 It made me smile that early on, she's battling with morality already, given that she does what she is told as an assassin.
