Ok, ok, so I was thinking and remember at the beginning of the movie where they are giving the gladers "test" like with taking Thomas's blood etc. they gave newt a shot of "vitamins" that he lacked in the maze. But we don't see Thomas and the others getting it, and it looks exactly like the same blue medicine Mary gives Brenda to delay the flare, SO what if newt was already infected and they gave him the shot to prevent the gladers to figure out that they were in fact wckd??
I SAW THAT, IM BETTING THATS EXACTLY WHAT IT WAS. MY POOR HEART CANT TAKE THIS
And also when I think it was Minho who said “I thought we were supposed to be immune” and someone else said “I guess not all of us are” I need to go see this movie again and pay attention to all the little details
