You and Barbara are both vigilantes. Both great friends and great teammates. You're both extremely close with one another. A little too close for there to be nothing in some people's eyes.
Tonight, you've been set up on a blind date by Dick, since you apparently don't have enough of a life outside your mask. So here you are, sitting at a table, all dressed up, sipping wine and waiting for the girl to show up.
When you suddenly see Barbara coming towards you with a huge grin. She's all dressed up, sexy little black dress, high heels, the works. She stands next to you.
"Hey! Can't believe I ran into you here. You on a date?"
"Yeah, Dick set me up with a girl. I'm still waiting for her though." You reply.
"Really? Dick set me up too! I'm a little late and I can't seem to find my guy."
A few gears are turning in your head at the increasingly obvious situation. You and Barbara are on a blind date with each other.
