Their only hope now is to escape without any problems ahead. ------------- "So how exactly are you going to get yourself over there?" "Keir said as he walked past Lone, with a small smile on his face. Lone silently stood there as she crossed her arms and rolled her eyes once more knowing what had to happen. Keir walked in front of Lone, grabbed her arm, and draped it around his shoulder, he then wrapped his other arm around her waist, pulling her closer to him. Soon they began their walk toward the ship, Lone suddenly had a mix of emotions, she didn't know what to feel, and she didn't understand why she felt herself heat up but this was the moment her life would change forever."
