When playing this game this teacher said to me-"I'll keep you safe" What does this mean?

In drama we were playing this zombie game and someone starts off being the zombie and then when you have to go around the room with your eyes shut and when you get touched you join the train queue, and I had just joined the train and had to find he next person so my teacher said to me: " Don't worry I'll help you find the next person to join the train,I'll keep you safe!" What does this mean?!
