Potential plate / wife friend sends a selfie of her ready for a graduation party she's going to. How did I do

So I'll be posting more questions about my situation. But basically I'm trying to turn this new single friend of my wife and I into a 3some/ fwb.

She texted us out of the blue a selfie of her saying "party ready". About 30 minutes later I replied "where's the rest". It was a head shot. She immediately responded youll get more later. I didn't reply.
