Guys what do you mean there isn't a fic where Thomas is watching the gladers through the cameras alone on his night shift, except he pays special attention to Newt (as always because they were lovers before he got sent into the maze and Newt promised him they would meet again) and it's the night Newt tries to kill himself.
And since Newt is like the only reason Thomas is even working for a cure anymore because Newt is his entire world, he impulsively activates the speakers that sound through the whole glade and yells at Newt not to do it and convinces him to get away from the ledge.
And literally everyone hears it.
Good news: Newt is alive and aware of his existence.
Bad news: his boys are also aware of his existence and now he has to help them escape from the outside while hiding his betrayal from W.C.K.D.
Also, he can communicate with them through the beetle blades because I say so and the grievers are his babies and he can order them around.
