Diarmuid nods, expression solemn, "The only way I know for people to go home is if they get really sick first. Sometimes, people get sent home when they aren't sick, but they always get brought back. I got sent home for a whole year and then was brought back here and only three days had passed," he shrugs. "I don't know if I understand how it works, but that is what happened. If it helps any, no one at home will even know you are gone. Time stands stands still for them while you are away!"
