Social Engineering on a flight to Baltimore

Be careful out there. Social engineering is a real thing, even on a flight to Baltimore. I was returning on a flight last night when this male passenger sat in the seat next to me. He was overly friendly and chatty so I shut him down. He changed seats so he could sit (and talk) with the woman across the isle. Over the next hour, I could overhear him engage her in casual conversation. Or was it? Listen in and hear a few pointed questions he asked and she answered.
