Killed

(Mark POV)
I woke up to dark running around the house trying to find something so I decided to check on him. "Hey you ok" I asked "mark it's coming back" he says in a in a panic. "Should we call light" I said try to calm him down "I TRIED AND HE WON'T ANSWER" he started to hyper ventilating "CAN'T YOU TELEPORT TO HIM" I yelled "it-it hurts mark" he says sliding down the wall to the floor "get up" I say as a idea pops up in my head *BING* "shoot it's Amy, I-"
I texted her back
AMY- MORNING
ME- hey I have some things to do I'll get a hold of you soon ;)
I looked at dark as he started to get up "what are we doing" he says "we're going to drive there" we ran to the car as we slid in I started the car as fast as I could and as we know it we zoomed out and headed to lights place.
(Time skip!)
We rushed out of the car and I tried to open the door with out knocking. Few seconds of trying to barge in I sighed and looked at dark...who wasn't there. "DARK!"
(Dark POV)
I tried to hold it in but the thought of killing would not stop over flowing my brain. When we got there I just watched in fear knowing that it was to late. Then it kicked in,the nearest house I saw I teleported into with full strength of evil,I saw a couple holding a baby on a couch. Then they finally noticed me when I started walking to them the woman screamed holding the baby closer to her and the man stood up and started to talk me out of it. I completely ignored him and pulled out a knife and stabbed him. The women screamed and broke down in tears waking the baby and the the baby crying to though at that point I heard the door open. I turned around and saw mark looking at the man who was bleeding to death and looked at me with a broken feeling in his eyes. I did care but the darker me didn't give a crap about anything. The women sobbed louder, then we made I contact between me and her the I looked at the baby "no, please not (y/n" the women pleased,Mark ran to the women and the baby and nodded once and then mark saw me about to take a swing at her. He snatched the baby and the women screamed in pain. I looked at mark again and he ran out of the house and back to lights house
(Marks POV)
OH MY GOD I sobbed to my self. I looked at the baby which by looking at its (e/c) eyes it was confused and sad, the tears came down her face. I looked back at the door, then I kicked it as hard as I could noticing that dark was done cleaning up... then I heard steps coming from the other side of the door. Bright rubbed his eyes while opening the door, then I ran in with the baby still in shock. Then I could not wait for him to slowly close the door so I shoved my back and closed the door and turned around quickly and looked at light who was also confused about why I have a baby in my hands "what happened" he asked I tried to cool my temper and explained everything that happened. He looked outside and ran out I decided to stay inside with I'm guessing (y/n) I shook my head and looked at the baby who was sleeping
(Light POV)
I felt so bad and stupid, then I got up trying not to cry and looked outside and saw him leaving the house and looking for the next one to ruin. I ran out of the house and grabbed on to his arm to hold him back. He tried to pull back but failed,I put my hand over his eyes and then seconds later he fainted, I teleported him to my lab and and grabbed the cure for him
