As soon as they reach sports house, he'll help with securing the door (Let's find a non-broken chair to shove the backs under the knobs), and windows until lock-down. Once they are safe, he's going to sit outside of the door leading to the basement(if anyone wants to talk to him, this will be the time).

Eventually he's going to get a message and then go down to the basement.

With everything happening, he's going to wind up crashing pretty hard.
