Lambert is Pissed - Witcher 3 - New Game+ - Part 93 - Following the Thread

This is a quest in witcher 3 called following the thread where geralt and lambert go to investigate the murder of lambert's friend Aiden . Geralt kills hammond but spares the life of karadin which makes lambert pissed and angry at geralt . I think following the thread is a great quest because we get to know some of lambert and few other witchers past history . Hippo Reddy
