The one where Adam asked what his name was not too much but when I first read it, it struck me as there's something special about him. Then there were a few other scenes. The one where Adam told him that Charles sent Mercy to Libor you could tell something. Because "Matt" hesitated and Adam told him if he knew something and if it wasn't a good idea to tell him now. The scene where he pulled Adam out of the dining room to tell him he was bit by the vampire. And then I missed it the first time but when I re read it when they finally made it to Libor his reaction told all.

But even before it was revealed that it was Bran I loved all the comments and statements that Mercy is Bran's daughter. That he is more protective over her than his own two sons. And even though Bran believes that he would sacrifice his own sons to keep the peace and his number one priority is the safety of all werewolves in the US and he would do anything to prevent an unnecessary war he would throw all of that aside if something happened to Mercy. Which he pretty much did. And him telling Mercy at the end that he loves her. Mercy and Bran's father daughter relationship has been my favorite thing in the series.
