Season 2: About Last Night

What Vincent speech doesn’t do is actually convince Sam, because he jumps! But
Vincent catches him. Sam is completely defeated and simply tells Vincent he
should have let him die. Vincent, saving Sam, shows that his beast powers could
be used in a calm, measured, heroic way. Catherine is  visibly moved by Vincent ability to control
his beast side while using it to help someone. I am glad and at the same time
disappointed by the conclusion of Sam arc. I think there was much more to
explore , especially about his relationship with Dana, his character and his
motivation. In the end, Sam just happened to be a victim of Muirfield’s
higher-ups. He’s no different than Vincent in terms of losing a part of his
life due to these beast-creators.
