I've been having this nagging thought in the back of my head for a while. I'm curious to see what others think.

The Team Rocket grunt from HGSS being able to start a family and have a child in Black/White has me wondering who else from the earlier games may have their own children. Will they appear in later games? The Idea has already been toyed around with by RSE and more recently with Benga in BW2. Imagine what the anime would do if a gym leader in XY or Gen VII jumps out and says "I learned everything from my mom. Misty!"
