It’s been a while since we’ve had any killer bugs. So this time round they manage to eat some guys head out and do a whole bunch of other weird stuff. Turns out some kid is controlling the bugs because, like his mother - they are half human and half bug. Monica manages to get herself cocooned by the kid, and Scully has a hard time explaining why their attic is full of human nests but in the end the bad guys skip town and nothing is resolved.
