Elliot is back...but for how long?

After Lewis & after the kidnapping of Noah, Olivia's life was finally normal as it could be. Then liv & her team went undercover to get a huge group of sex traffickers. Little did she know that an old friend was there...Fin, Kat, & liv went undercover while Rollins & Carisi stayed in the van & waited to arrest the traffickers & they talked a little ;) Okay in this fanfic Rollisi is going to finally become a couple & Elliot will be back. So a little warning there will be some mentioning, talking, & description of rape. This is my first time writing a fanfic so I hope you like it & comment what you think & what you want to see happen- Bye sincerely Elizabeth :)
