Indirectly introduced to his kid?

This guy at work and I like each other a lot. He's divorced with a son. When we were together at work the other day, he called his son in front of me. I noticed he moved the phone to his ear closest to me and I could hear the convo. After their call ended, we talked about his son and the conversation. He's talked about his son before, but this call at this point seemed purposeful. Was he indirectly introducing me to his son?
