User blog comment:BenRG/New Teaser Pic From Monty/@comment-4010415-20140324231806

You know what's funny? Back when Goodwitch explained that they'll store their weapons in their lockers or whatever, I thought "Well, that's stupid. What if Beacon gets attacked by grimm or something? Are students expected to run like hell to the locker room and hope they don't get cornered?"

Considering that Beacon was circled on that map in the end of episode 8, I think it's safe to say that Beacon may be attacked at some point or another. Whether the students will be there or at the tournament or festival, it's hard to guess.
