Taking over Cragens place in the office was a major step for Olivia but as the years went on she was more comfortable, being the lieutenant changed Olivia a lot, in some ways that people wouldn't even know who she was anymore. Though the words she always said to the victims were the same the tone she used to talk to them in had gone, it was different she often had to hurt victims even more emotionally to get men convicted. She often sat there wondering why she didn't just leave the job, to try something different, she had watched multiple people come and go out of the precinct over the years. She even found herself looking out of the office window looking at the desks smiling seeing herself and the old team sat down working, sometimes even laughing when munch said something funny, she missed the old team. It was always her, stabler, munch, cragen and fin. She knew sonny and Amanda were great detectives but sometimes she wished it was back to the way it used to be.
It was coming up to her birthday and she wanted nothing more than a get together with all her friends, old and new, but she knew that might not of been possible due to them all having new lives. Fin knew that she wasn't always happy with the way things were and wanted things to go back to the way things were, he often felt like that to. After hearing her on the phone to her friend about what she really wanted he decided to make it his personal mission to make sure his best friend got what she wanted for her birthday, so he then began planning a birthday surprise for her getting people to help booking places and ringing Alex, casey and the others to make sure they could make it. He was a little hesitent at first about calling Elliot not knowing how liv would react if she saw him again but he did anyway.
Some had got back to him within minutes to tell him they were on board with his plan thinking it was a good idea.
