Repression

You tell her you want her to meet your Mom. You still got her on your mind. You have to show her that what she wants can't occur! And by bringing Jessica home, you'll be able to show that. Of course you're really nervous about what's going to happen. You barely manage to keep yourself from throwing up again.

Jessica meanwhile is a little puzzled by your choice of "date" but agrees. You get home and you and Jessica talk for a little while longer getting to know each other better, but still in the back of your head you worry about Mom.

Then she arrives. And she looks really surprised to see you with a girl in the house. Speechless in fact.
