[Alan looks up at the sound of another’s voice and finds a stranger sitting at the camp’s perimeter watching him. Well, watching Bit, more accurately.]

You could say that. [Now that the blue shape is no longer zipping around, its possible to see that it isn’t completely spherical. In fact, its surface is in constant motion, shifting between complex shapes almost too quickly for the eye to follow.] He’s a bit. Came through the Ingress a few weeks ago. [‘When we still had an Ingress’ is the unspoken, unnecessary addendum.]

I figured he could help with the watch tonight.

[There's nothing in particular about the floating blue shape that suggests it's a 'he' or even that it's alive besides the fact that it's moving. More likely that designation has to do with users' anthropomorphizing tendencies.]
