Maybe Cordelia because awkwardness plus not thinking it's the best place for her. Though he doesn't know she's dead yet. Of course he has seen bringing people back from the dead go bad and good/bad. I'm not sure he'd want any dead returns. He already has to deal with Angel. He'd rather not have Spike too. But then of course there is always his family. He never wants to see them!
Also, aww, protective Reid!
/cheats Who would Reid least like to see from home?
