Well do note a pokemon has to give consent if it wants to tag along with them. Being caught just makes things easier following them around. Plus it seems Gengar is more fond of Ash than the lab residents.

Honestly looking at the preview I think one scene when that couple is standing before Ash, I think in the same scene Gengar shows up threatening them with a Shaow Ball. I think those two were picking on Ash and Gengar defended him.
