Yang: "Weiss a two-headed snake crushed a bakery I wouldn't count on it." 

Ruby: "Plus I mean we didn't solve everything a lot of people were hurt, and we still don't know why they did this."

Weiss: "Well not every story has a neat and tidy ending."

Blake: "Yeah just like the Team that went missing long time ago." 

Ruby: "I always wonder what happened to that team.' 

Blake: "We never know, but we might not have all the answer, but we do have a lot of dangerous people behind bars and I think we could be proud of that." 

Ruby: "Yeah and if anyone tries to do something like this again we'll be there to stop them." 

Yang: "Yay, teamwork, camaraderie, good guys, go team, alright, good job... So what now?"

Weiss: "Well I suggest training for the tournament, but I guess we have that cover at this point." 

Blake: "So then?"
