Zoe had a surprise visitor last week, and now they won't go home. It's certainly nice to have help around the bunker. But this one seems like he might be more trouble than he's worth. Luckily, there's no room for him in the Zoe Zone so everyone (especially Zoe) can have a much needed break. Apocalypses are hard enough without have to deal with these types of awkward social situations when a guest outstays their welcome.
