The escape process proves uncomplicated: you just run like hell out of the bedroom, without looking back. Amber and Mary Lynn have remembered Clyde, and for a second you're terrified that they'll remember you, but that doesn't happen. Of course, neither of them really care about you, whereas they want to get revenge on Clyde for all his sins, real and imagined. You thank yourself for staying so still while in Mary Lynn's bra, as apparently it paid off and she really did forget about you.
By the time you stop to catch your breath, you're already outside the master bedroom and well down the hallway. You give yourself a few seconds as it appears the giantesses aren't chasing you. You don't want to linger though, so you start jogging down the hallway again.
Thankfully, Amber and Clyde's house is only one floor, so you don't have to figure out how to get down a staircase. You reach the front door in about ten minutes, and when you do, you stop and look up as it towers ahead of you. The giantesses left the door wide open as they came back in, not even bothering to shut it. They really are heedless.
What on earth are you going to do? The police and probably the army are going to show up eventually, but they're more likely to squish you than see you where you are now. And frankly, even if the giantesses don't get you, they might very well blow up the house instead of trying to take these women alive.
On the other hand, what's your alternative? You could go outside, but you might not be any more noticeable there. And of course you run the risk of being the prey of whatever insect or rodent is outside. Still, even that may be safer than where you are now.
