Hold on, One year time skip, Gray went Dark, Natsu looks worried and wants to go to Sabertooth.. could it be that the one who kills Frosh is Gray? i mean that's the only logical explanation to why Natsu suddenly wants to go to Sabertooth since he knows the killer's name.. So Natsu will go to Sabertooth to prevent Gray from killig Frosh. I'm calling it.
