A big criticism of the last season was the fact that Nicky - played by Natasha Lyonne - was hardly in it. She was carted off to max after trying to do a heroin deal with Officer Luscheck, and he ended up ratting her out. We kept waiting for to reappear, but it never happened. With Stella also headed to max, there could be a chance of seeing scenes taking place there with the two of them, but preferably Nicky will be coming back into the main prison fold before too long. With Big Boo now besties with Pennsatucky, Red possibly hooking-up with Healy, and Morello married, a lot has changed for her closest friends since she left, and itll be interesting to see how she reacts to all of the new dynamics (probably with a hilarious sarcastic remark). Theres always the chance she wont be seen again, but thats not a possibility anyone wants to think about.
