Haven't you read the Bible? "He" is obviously Jesus. No one else is ever referred to by dramatically formatted masculine third person pronouns. She doesn't want to run into Him because, as we all know, Jesus hates gay people. That's His whole thing. His most famous line is "hate thy gay neighbor" or whatever and everything.
So, if you're going on a lesbian date, you have to be careful not to run into Him. If He spots you, His neck will crack and His head will snap to look directly at you until you leave His line of sight. During this time, while He's watching you, your REPENTANCE METER will increase, and if it gets too high, He'll start dashing towards you on all fours, His head spinning around as if it were a mask hooked up to a motor installed directly in the center of His skull.
You can try and hide in whatever naturally placed giant lockers you happen across, but if He catches you, He grabs you with every one of His thousand arms and transports you to the HALLWAY OF THE CHRIST. Here, you have to run to the other end while Jesus tries to kill you with His laser eyes and AXE OF THE DEARLY CRUCIFIED.
And even if you make it all the way there and make it back to wherever you were when He caught you, your REPENTANCE METER's maximum level will have decreased by 50 points, making it harder to run away the next time He spots you. And if your REPENTANCE METER's maximum level reaches zero, then you immediately become christian and over the next four weeks are evaluated for the possibility of becoming THE CHRIST's next host after He is inevitably killed by some high schooler.
And they're demons, too, so, yeah, meeting Jesus is something they definitely don't want to do.
