Seriously, they don’t seem all that stressed by having a blood-sucking alien stomping around hanging people upside down in the greenhouse and shredding up dogs to feed the podlings that will take over the Earth. I actually started to suspect the woman *was* a podling, so insignificant was her fear reaction to these events.
But it was kind of cool that she didn’t faint.
And she tied her boyfriend to a chair, so that’s good.
