This episode was very unique and I adore the idea of crossover, even thought I did not knew it at the start and now I am excited to find out what happened.
Susan storyline and her trip to New York - it was somehow the best part of this episode but I cannot say that other storylines were not interested. Specially Romano one. My little sister even said that she think Romano is one of the most interesting characters and her favorite as even though he has been main cast long, we do not know much about him and he is such a mystery, looking like the worst person you could ever met but then, when it is needed, he can be so caring. And Pratt and Gallant. Poor Gallant, manages to get him into problems where he don't have to be. And Pratt just cannot take the responsibility.. And he just cannot understand there might be problems. And the Mallucci, for comparison them. Mallucci was good heart and somehow joyful and not that kind of..arrogant.
And Abby storyline. her drinking.. it can be interesting
