It happens before the maze trial.

You are Ava Paige's daughter, but you are still an immune subject despite having some advantages over the other subjects...but you made friends with them, especially with Gally who sometimes did some small jobs for W.C.K.D. like taking care of the internal garden area or fixing some simple things around the facility. The boy was sitting at the table having dinner alone. Gally didn't have many friends besides you, Minho wasn't really a close friend and the others were just acquaintances. Gally didn't even spend much time with them because he didn't spend much time in the classrooms or in most of the common intellectual tests...his thing was strength and practicality. The one he saw the most was Minho because they did the physical tests together. But something with you was different...
