Re: ANYONE ELSE?
At the edge of campus, Hopper just popped in and was out of breath, amped up for a fight against a monster that suddenly disappeared. He ran off in search of anything or anyone for help, when he found a phone and the note nearby. He's still in adrenaline mode so he wasn't in the mindset to accept what was happening, which found him running headlong away from the campus and towards the mall. When he realised what it was, he went looking for people, food, anything useful.
