Minho when Gally attempts to rid the glade of the biggest threat he believes exists: you. It may be more than a coincidence that as soon as you arrived, things started to go downhill for the gladers, but Minho wouldn't let that justify Gally's actions. You were innocent, just as each and every other glader was. None of them asked for this, and he would protect you no matter how the tides turned.
"Watch it, Gally. Keep your hands off her."
