Where is he?

Part one

I lost my mind and I dint know it yet, everything Deathstroke said for me to do I did. He took the chains off and I kneed down in front of him.
" Good apprentice " Said Deathstroke smiling
" Stand " he said. I stood up.
" Follow " Said Deathstroke. Deathstroke started to walk out of the room and into another. He took me to a room and said it was mine,
"This would be your room " Said Deathstroke.
"I will train you more than you already have your going to be trained how to kill people" Said Deathstroke. Deathstroke walked out of the room and closed the door. I walked over to the bed and sat on it.
About two minutes later Deathstroke summoned me and I walked in and he started training which lasted all night.

Nightwing pov:
I went on to contacts the screen and barbra stood next to him.
" Nightwing to justice league. " I said
" Justice league to Nightwing, what's wrong?" Wonder woman replied
"Oh hi Wonder woman, um.." I said I went silent for a few seconds and said
" Um Robin went missing two days ago and batman hasn't slept for that but hes a bed now and he dint want help, he's look around gotham twice and is determined Robin is in gotham , but I want you and some of the other justice league to come in three days and help him out. " I said hoping she would say yeah.
" Yeah I will ask Flash, Martian Manhunter, Green Arrow, Superman and Aquaman if they wanna come to okay " Said Wonder woman.
" Okay see you than " I said
" see you than" Said wonder woman
I ended the call and spun around on the chair.

Bruces pov:
In the morning I woke up and walked down the stairs to the batcave and dick was asleep on the desk of the Batcomputer. In the middle of hacking into cameras in Metropolis. I walked up to dick and shook him slightly.
" huh" Muttered Dick
" Oh hi Bruce " Said Dick
" What where you doing ? " I Asked
" Look if a camera spotted him" Said Dick
" Did any" I said
" I dint get to look " Said Dick Turned around on the chair and started to type again then he looked on a camera.
" Found anything " I said
" Nope" Said Dick
Bruce huffed .
Two days passed and in that time Deathstroke trained Robin and now he killed who ever he was told to. Robin wore a black mask that covered his whole face (a little like jason ' s when he was red hood )
