Olivia was sitting at her desk when her phone she answered this is what she heard

O: This is Dectective Benson

L:Hello Olivia

O:Lewis? How did you get out of prison

L:Oh say hi Olivia.A small girl frightingly whispers "hi" and Lewis says See You Soon Olivia

After Olivia heard this she dropped the phone and went into a minor state of shock and then Nick ran over." Liv who was that".Olivia stutters" I-It Was Hi-Him""Who Olivia".Nick practically yelling now and right after that Olivia passed out."Liv..LIV Call A bus NOW!"

At Mercy General Hospital

Nick,Cragen,Amanda,Fin, and Munch all sat in the waiting room

"You must be here for Detective Benson correct" Cragen then stands and continues on to say"Yes mam, how is she?" She went into a stage of shock and I assume that whoever yelled at Detective Benson triggered a flashback due to her PTSD"Suddenly everyone looks at Nick who frowns and then says"May we see her." "Yes, she is in room 112" " Thank you doctor" and they all head to see was lying in the hospital bed thinking everything suddenly realizes everyone is in her room and mutters a "hi". Nick stand up and say" how are you Liv" "I'm fine Nick".Even though Nick knew Olivia wasnt fine he went along with it"Thats good, Now Liv we need you to tell us who was on the phone" Olivia then stutters"I-It was has my neice Olivia ." and thats when cragen blows "Rollins go to Rikers see how he go with Fin to the hospital he was staying go get his file and Olivia...just go home and do not leave your apartment until further notice."But" "no buts now go home"
