Ethan was, unsurprisingly, rather pissed with Aren's casual 'attitude adjustment', via a book to the back of his head. More than likely, the initial reasoning for his standing up was probably to try and beat Aren's ass... Despite his reputation for winning fights. But, moments later, the action became rather similar to Aren's own- A headlong rush for the door as the student burst in. Shockingly, it didn't seem to be an effort to save his own hide. He was merely in a similar rush to see what had happened, maybe help save Tristan's life... But it would not be so.
As both boys- along with a large majority of the other students- reached the door, it seemed it would only be to see Tristan's last moments. Ethan crouched at his side, wide-eyed as Tristan's gaze went skyward. He tried to choke out a few words past the blood roiling into his mouth from the bullethole in his neck, but found that nothing came. No noise escaped him but a quiet gurgle, and then his eyes went dark and empty, the life leaving his body just as tires squealed near the entrance of the school, a sleek black sedan peeling out of the parking lot and barreling down the snowy streets, away from the crimescene. The driver couldn't be seen... Nor could anybody else in the vehicle. Suddenly, Ethan felt a lot less secure in thinking that the "Movie's Mafia" wasn't involved. He turned a hopeless gaze to Aren.
"You're supposed to be some kind of genius, can't you do something?"
There was... Actual distress, in his tone. Even with all his snarky comments, all of his self-absorbed moments, he really did have some form of a heart... If a small one.
