As soon as he saw Angela's name appear on the network, Genji had already started walking. Vallo seemed to be collecting people from his home world and he didn't particularly know what to make of that - whether or not it was something directed or something that happened to be merely a coincidence. He had learned a lot in the short time that he'd been there - number one, he was a video game character. For some reason, that was the least shocking of all and either he hadn't processed it yet or he simply didn't have the energy to care about it with the multiple other questions brought to the front by Vallo. It wasn't hard to find out the very recent history of people being sent to the past and trapped in alternate dimensions - it was dangerous.
He'd learned of the danger himself within his first few days there, in fact. Monsters seemed to roam the forest and while they weren't desperately dangerous for him, they certainly weren't something to sniff at. Angela would have her work cut out for her here if things remained at the pace they were currently at and as selfish as it was, he was (in part) relieved that she was here. She didn't seem to have a casual understanding of this kind of world-hopping like Jesse and his girlfriend (still weird) did and on top of being one of his most trusted friends, she was the only person who knew how to fix him when he broke - because that's what he did, wasn't it? He broke down. Not an injury, but more like a machine or a particularly temperamental car.
He was wearing the designer clothes he'd ended up splashing out on when he'd gotten a sudden windfall in the last week and had opted to spend it all on absolutely useless things for some reason, his hoodie pulled up over his head and his hands stuffed into the pockets of the sweatpants he'd bought as he was directed to Angela's room in the flats, knocking twice on the door and briefly wondering if he should have taken the time to let her know he was coming.
