You and Gally were inseparable in the Glade.
You loved him, he loved you, you loved each other. You dated for months. The day that he got taken by a griever was the day you thought would be the worst of your life, until a day later he threw a knife at Chuck, killing him and causing him to be beat up by Thomas.
Your days in the Scorch were miserable, as well as your days in the WICKED building. Of course you knew you had to be strong and help your friends, but still felt horrible inside.
That was until the day that you escaped the building with Thomas, Newt, Minho, Brenda, and Jorge, and landed on Denver, where you were told all your other friends were.
Your group was handed a note, and invitation to meet the leader of the Right Arm. You couldn't believe what you were seeing when you read who had written the note. Gally.
With a million thoughts going on in your head at the same time, you and the others went to the location indicated, where you were greeted by Gally. His face was still haggard from when Thomas beat him up, but he was with no doubt the guy you dated in the Glade. He invited you guys in and told you to wait for the leader to come. Meanwhile Thomas started asking the questions everyone was thinking.
