Honestly if I was Eren I would've taken Levi very far away where no one could find them. That way Levi would've never been able to find them. Plus if they go beyond the wall Eren has that really cool special ability he can control titans with. So he could use that. And if Levi ever went missing he could call the titans and make them find him and bring him back. Just saying ╮(￣▽￣)╭ (I would never do that to Levi... Maybe Armin...)
