Note

                                    

                                          
I run into the DEO and straight over to Winn, who's scanning through images and security tapes.
"Alright Winn what have you found?" I ask, removing my coat and revealing my DEO clothes, and hoping onto the platform surrounding the table. 
"The place from the video was at this post code gj6 o2c which is also known as the abandoned post office factory, that shut down years ago after an accident killed 10 employees and injured 100s of people and the government just decided that it wasn't safe so they closed it down and no one has been in it for about 9 years now." Winn says showing me on the map the place and a few newspaper articles about the accident, I skim read them, I don't really care to be 100% honest but it's quite fascinating, don't you think?
"Okay I'm going there right now." I say dropping the coat on the floor and getting my gun out and placing it in my trousers.
"Okay Alex call me if you need back up," jonn says smiling and patting me on the shoulder as he walks past and into my lab, then he walks out again, looking quite embarrassed and he walks across the corridor into his lab, I think he got confused between my lan and his lab. 
"Okay I will thanks jonn" I say smiling back
"I'm coming with you" Maggie says grabbing her gun and walking over to me,
"Okay" I say and then I look at Emma, "maybe we should bring Emma as well, as in she has a gun and magic which is kinda better then we have" I say pointing at her.
"Sure I don't see why not." Maggie says shrugging her shoulders. 
"Emma," I say looking at her, "do you want to join us?"I ask. She nods, and I see a smile creep up into her face and she walks over and kisses Henry on the forehead before running over to us,
"Lets do it." She says grabs her gun from inside her red leather jacket and pulling it out, and we run of to the address Winn has given us, and has even wrote down for us even though we are both wearing ear pieces. Then we run out of the DEO and straight to the post office factory.
                          
When we arrive the whole place is bordered up, there's giant wood boarding up the only door, we can see and all the windows have been boarded up as well, with crosses of the wood. There's no sign that anyone has been in until Emma spots a broken window at the top, I then attempt it kick down the door and I get most the way in but Emma uses her magic to get into the last part. All 3 of us storm into the building with our guns and lights shown. I'm resting my gun on my other hand and aiming at all places, being always ready to shoot. There's nothing in the place except the old machines which are coved in dust so thick its like fur, and all cobwebs are strung all over the ceiling. It's a very spooky environment. A lot of people would feel almost as though that place is haunted as it caused 10 deaths but since I'm used to finding dead bodies or killing people it doesn't scare me. And I'm sneezing like crazy.
                          
Then out of the corner of my eye I spot a white envelope, it doesn't look old it's look new, so I aim my gun at it and walk over. I look at it. It's has my name written on it in black swirly writing, I open it to discover a letter with the ending from Harbinger. I read it, it says 
To Alex,
As you know I have your sister and since you are smart I thought you might find her here so I took her away, and left you this note. You have 37 hours left, you shouldn't be wasting them by going places you don't need to go. Now unless you realise all the alien prisoners at the DEO I will kill Kara and your never see her again, if you solve this riddle it might lead you to her, you have a friend, buisness and money money knows Kara, super, brother, money girl. Good luck time is ticking.
Harbinger your not so good friend. 
Tick tock tick tock.
                          
I wave to the others to show them that I found something, they run over, Emma reads the letter and then passes it on to Maggie and she reads I to, I'm wondering what the riddle means when suddenly I hear an alarm going of, it's ringing loudly, so loudly that's I have to put my hands over my ears and I realise that once we have found the note the alien had made a trap so that unless we escaped now, we would be squashed, we will be killed unless we run now, unless we escape.
"Run!" I yell grabbing the letter and heading straight for the exit. I can feel dust and little bits of metal and wood falling on my head. We run out the building and all breath a sigh of relief, Supergirl wasn't in there but there was a clue and a riddle that will lead us straight to Kara but I dont get it and neither do Emma or Maggie so we decided to return to the DEO and find out if jonn or Winn understand it, but first we turn around and suddenly the whole post office falls in on itself, creating a thick cloud of smoke. Once it's cleared all that's left is rubble, then the sound of police sirens come, and Maggie puts up her gun along with me and Emma as we pretend to be investigate, not that we caused the whole place to topple down. 
"Officer." Maggie says looking at him and shaking her head. "This is an unidentifiable accident we believe the roof might of fallen in and destroyed the entire place, no body was in there when it collapsed. You can investigate further with my help in 5 minutes." She says waving at the office and instructing all the others to put there guns down. We walk over to a corner and Maggie says "you and Emma go back to the DEO I will be there but let me investigate, love you Alex." She says smiling and turning round to look at the officers and the destroyed building. 
"Love you to Maggie, see you at the DEO in 2 hours let say." I say kissing Maggie on the chin and Turing back to Emma, Maggie runs over tot the rubble and the officer while me and Emma run back to the DEO.
                          
When we run into the DEO, we come across jonn.
"What did you find Alex?" He asks looking at me with his eyes full of hope and tears.
"A note from the alien that took her." I say reaching into my pocket and trying to grab it out,
"It's got a riddle about where she is but none of us understand." Emma says pointing it out on the letter, and reading it. 
"Do you have any idea about what it is?" I ask jonn, feeling hopeful that he might know something. 
"No, I'm sorry Alex I'll ask everyone else, someone may know." He says shaking his head and walking over to everyone, I get worried as more people shake there heads, then jonn comes over. "I'm sorry no one knows." He says. I'm so mad I grab out my gun and shoot it at the wall. I almost hit Winn in the head,
"Excuse me!" He says, pulling the most priceless face I have ever seen, I have to bite my lip to stop myself from laughing out loud. 
"Sorry, I'll go downstairs to shoot" I say and Emma follows me down the whole time humming something.
