What's odd? This is just a picture from the Madrid overnight.
The older guy in the middle is obviously an ER Captain with his young FA girlfriend (on the left). The guy on the right is a junior FO on the ER with his Cougar FA girlfriend. I mean, they ARE wearing Red Dresses - jeesh guys. You can't tell from the angle of the shot, but they are wearing their Sub Commander suits.

The guy in the middle? The gay FA that everyone gets along with.
