Lisa posted the Bestest Clip Ever. You know the one where Monica Quartermaine finally tells Sonny to go to hell and that he's responsible for all the deaths in her family. Well here is the second Bestest Clip Ever and it comes from the same episode.
In it Sonny FINALLY admits that he's destroyed the Quartermaine family. Fast Forward to minute 5 in the clip. It is so worth it to see Sonny (and in my opinion, TPTB through Sonny) admit that they have destroyed the Quartermaines.
